Completely agree.

That reads a little like the zeal of the convert. The US is still a more humane nation than most, though it's not immune to the diseases that come from being a great power.

I don't know about that. Honestly, idea of Americans self-ranking themselves as more humane is the kind of absurdity that lead us to where we are today. How many people making such claims have actually travelled to the nations they villainize?

For a long time I wanted to believe you, and in the past I'd have looked at work camps in China and said "thats bad". Now i look at the US prison industry and go "Is it really that different?". The examples don't end there...

Russia invaded Ukraine.

You can make the (somewhat weak) case that Russia was provoked, but the first violent strike was made by Russia and Russia alone.

piloto_ciego•35m ago
We certainly didn’t help - but I’m wondering if this wasn’t inevitable after the Russian invasion of Ukraine?

Totally not a fan of the guy we have driving the bus right now, I didn’t vote for him, and oppose all war. But now that we’re in it, I’m a bit concerned that this is going to be quite a bit more violent and terrible than we have the stomach for?

I mentioned above I work with some Ukrainian refugees. We are not prepared mentally for what is coming.

Lumich•3m ago
The US had been preparing the Ukraine for war long, long before the CIA mass murder incident at the Maidan.† The violent protesters were trained in the Baltics, maybe elsewhere too. That was not spontaneous but tightly organized. The US was in full command as became clear from the Nuland/Pyatt phone intercept. “The most blatant coup in history,” as a prominent American observer remarked whose name I can't remember right now.

† See Italian journalist Gianni Micalessin who dug out the Georgian snipers that were hired to shoot at both protesters and the police so as to “get the ball rolling a bit faster.”

lynndotpy•57m ago
This is a BBC article about the UK being at war. Not the USA.

That said, it argues that the various pre-war preparations fail to include "psychological preparedness". I think this is largely true for America as well, since war is something that the USA almost exclusively engages in offensively in distant countries, with only one small exception for one day on 9/11.

piloto_ciego•37m ago
I know, I read the article I’m just saying, we Americans have no idea how big of a conflict we’re in right now, and we are not psychologically prepared for what it will mean to be bombed by hypersonic missiles or shaheds or what have you either.

I work with some Ukrainian refugees, we are not prepared.

It's amazing that despite russia constantly attacking European countries, we still allow their propaganda and fifth column russia-adjacent political parties to prosper. It's about time Europe wakes up.
gradus_ad•55m ago
The simple truth many have come to realize is a European leadership that insists mass migration is not a problem and head-in-the-sand denies the critical importance of cultural unity and shared identity for the maintenance of stable and liberal democracies is a much clearer and present danger than Russia.

War a nation can recover from, but from an erosion of cultural unity and shared identity it cannot.

bdangubic•53m ago
Cultural unity and shared identity is cause of many (many) wars…
Lumich•27m ago
They're not. Rather, the organizers of war – typically rich and powerful people in or close to London or Washington – use their propaganda networks to play these popular cards of culture and identity. Don't confuse the cause and the means.

This is just a fearmongering article.

azan_•59m ago
> russia ? lol, they can't even manage Ukraine ( with our aid )

And that's why they want to attack Europe. They hope that it will either cause eu to stop supporting Ukraine or at least that it will give them good negotiation position (e.g. we'll stop attacking baltic countries but Ukraine has to let go of their territory).

net01•56m ago
if they end up attacking Nato, I think we would just go until boots are in Moscow. our tech is better and we have more men ( we dont need North Koreans to fight)
torben-friis•52m ago
If our boots get anywhere near Moscow we get nuked.

That's the issue, a belligerent neighbor that permanently sabotages you but which you can't ever get too close to losing.

troupo•54m ago
Russia has been probing NATO for several years now. NATO is a paper tiger that seems to be content to do nothing. As long as the probing is in the lesser members: the Baltics, Romania.

When (likely not if) Russia decides to attack the Baltics, NATO will just shrug and send a strongly worded memo.

Russia will never start an open war with the UK or any EU country. They can barely handle Ukraine imagine that plus any other country.
Lumich•11m ago
If it were only the Ukraine the war would have long been over. The West block has supplied more than $500 billion in aid to the Ukraine, that's more than twice the US lend/lease to the Soviet Union in 2026 dollars. Plus intelligence information and probably other things I'm forgetting. The more dollars are sent to Kiev, the more blood and lives the Ukrainians are expected to invest. That's the deal.
nickdothutton•55m ago
It is my current view that this BBC article and the recent announcement by national security advisor Powell are conditioning the public mind not for an actual hot war, but for a "tough winter" of eye-watering price rises, possible shortages, and maybe even utility supply problems if we are particularly unlucky. While talk of war increases, a glance at the state of the military suggests to me this is unlikely. What we have is rather limited, and even that is only about 1% deployable within 6 months. Much of Europe the same (Poland being an exception).

That said, I also believe that there is fairly widespread, low intensity, grey-zone action across Europe at the moment. Not every random fire or infrastructure failure is "The Russians", but I'd be surprised if none of them were. Indeed some of them have already been formally attributed.

largbae•54m ago
Seems off-topic for HN, but let's look at it technologically: if Ukraine and Iran have demonstrated anything, it is that drones are like guerilla warfare squared: even the smallest player can land hits and deny areas to the largest forces.

It might be tending towards impossible to achieve regime change militarily at this point. Maybe we all should just figure out how to get along.

justinhj•53m ago
Russia is a nuclear power
ajb•49m ago
This article shows the biasses of the press. Everything is about public perception, so the problem is that the public don't perceived that there might be a war. This is stupid, public perception can shift very quickly. The actual problem is not maintaining investment and critical industries. The UK was able to shift commercial manufacturing to wartime production for world war II. That doesn't work if you've offshored everything.
specproc•48m ago
We've been in one war or another for most of my adult life.

We are in a perilous position right now in Europe, very close to a major escalation of the Ukraine conflict. This would entail direct conflict between nuclear-armed powers.

I find it deeply troubling that no mainstream party in most European countries seems to think this is a bad idea.

sgt101•47m ago
I think all of them do, but the alternative is to let the Russians do what they want and that ends worse for all of us.

> Threat from Russia

Right. Mighty Russia that has been fought to a standstill by its much smaller neighbour is going to provoke a military alliance absolutely dwarfing it into outright war. Not even China is going to back that after having a look at who the more valuable trading partner is.

Being ready for war is reasonable, being afraid or worried is a waste of time, and even irrational in this case.

Some people said two days, some said ten days. Russian officials thought they would get a short war, and they were wrong. Wikipedia will point you to a bunch of references.

A Russian war with Europe would not be the short war that the original poster alludes to by invoking statements from a Russian official.

So do the oligarchs think the Ukraine is finally losing and their investments falling to Russia? Time to send in the sheople to save their chestnuts?

Yes, there is a war, the same that Warren Buffett famously referred to – a class war.

mmooss•30m ago
A major difference, IMHO, is the abandonment of the rules-based, rights-based, international order. Within it, international war (as opposed to civil war) was nearly impossible - it hardly existed for generations. While you need to prepare for the worst, you need to work for the best, for progress, like so many generations before us in much more difficult circumstances. Preparing for warfare doesn't mean accepting it; we must also work for freedom, including a just peace. It doesn't happen without work.

Again in this era, reactionary and nationalist messaging has dominated and somehow, despite generations of extraordinary success, despite being born into it and seeing its success and superiority, many/most think such an order is infeasible or even undesireable. At the same time, I've seen American leaders in the military industry advocate for becoming accustomed to mass destruction and death.

And shockingly, even the experts and practioners abandoned it and at nearly the height of its success. It's as if a messaging campaign insisted cloud computing was impossible and absurd, and so everyone just stopped using what was obviously working. For the rules- and rights-based order, yes there were outliers and setbacks and threats; that's life. But the entire free, wealthy, industrialized world subscribed, and were untouchably allied, free, safe and prosperous. Now, having abandoned it, all those things have diminished.

What's missing is not acceptance of warfare but ultimate commitment and work for freedom and peace.

nullorempty•26m ago
Most of you who rah-rah-rah against Russia would not pick up arms and go to war to protect whatever you believe your democratic values are.

First of all you don't even believe in democracy - if you did, your views would not be so one sided and you would really want to understand the conflict.

Secondly, because no real democracy is left anywhere in the world. It's a myth.

This is a British article for Britons. The British press is nuts: everything is taken to extremes: events, statements and political moves. Unfortunately, every day the USA press grows more like the British press, moving leftward and increasingly alarmist.

Take Rolf Dobelli's advice - don't listen to the news:

This idea that you can delegitimize democratic parties by making some handwavy motions backed by little to no evidence claiming they're controlled by Russia needs to die, because they're an actual and definitive threat to our democratic systems. The Nash equilibrium maintained by political parties in certain systems deserves to be disturbed, because the situation in some European countries (I live in Europe) has clearly been on a downward path for the past one to two decades.

It's amazing that we are still blaming one side even though Europe supplies shit loads of weapons, intelligence and shit load of money to Ukraine to continue the war.

How do you say that in Russian?

I'm sure you think this is smart, but the indisputable fact of how this conflict started remains.

Are you suggesting that we don't come to the aid of our friends when they are attacked by our adversaries? That Ukraine does not have the right to support? That it must succeed or fail on its own or it's somehow not sporting?

nullorempty•34m ago
What were the Minsk agreements for?
azan_•28m ago
Good point - we must remember that russia attacked Ukraine already in 2014, Ukraine agreed to their conditions and it still did not prevent russia from wanting more. History repeats itself - appeasement never works.
carefree-bob•22m ago
The EU overthrew the government of Ukraine, with violence, using paid assassins and mercenaries to shoot members of the police and government officials, driving the President of Ukraine to abdicate, and appointing a puppet regime in its place. Then this puppet regime began a series of mass executions and ethnic cleansing campaigns against Ukraine's ethnic Russian population.

That was the second attack. The first attack was the western organized "orange revolution", one of the CIA organized color revolutions, that was also backed by violence, in order to drive out another duly elected official.

In response to the Maidan coup, Russia provided some token military aid to independence groups in the Donbass, that refused to honor the appointment of the Maidan government and demanded the return of the elected leadership. The EU/Maidan regime sent in tanks to shoot the protestors and seize the regions by force, taking approximately half of the territory, and launching a 8 year bombing and terror campaign against the Donbass, leading to over 2,000 civilian deaths a year killed by EU/Ukrainian forces. These attacks included burning Russians alive in the so called "Odessa barbecue" celebrated and put on restaurant menus during 2014, beheading Russian speakers, burying them alive, etc.

In 2014, on the verge of defeat, the EU/Ukraine forces agreed to a peace treaty in which the Donbass militias would pull back and Ukraine would cede sovereignty to them while keeping them officially in the country. On video, all the major European powers that signed these agreements - France, England, Germany, admitted that they had no intention of honoring the Minsk agreement and instead they needed time to rearm the Ukrainian military for a final ethnic cleansing of Donbass. Russia reduced its support for the militias and they withdrew, but Ukraine never honored the agreement, and continued to shell and bomb the civilian areas of the Donbass for the next eight years, dropping petal mines, dropping bombs, and constantly shelling the rebellious cities.

Finally, after eight year of these terror attacks, Russia said "enough" and declared war on the Maidan regime, and together with the Donbass militias, it launched an attack to overthrow the illegitimate government of Ukraine, and bring to trial the western funded forces that were ethnically cleansing the country.

azan_•19m ago

fabian2k•42m ago
Russia invaded a sovereign country. Period.

Europe and everyone else is entirely justified under international law to provide assistance to Ukraine to defend itself.

Regarding your edit, Russia doesn't have the right to dictate neighbouring countries which alliances they can form. What you're doing here is denying Ukraine its sovereignty, just like Russia does.

The US lacks the political will for a war with NATO, I'm speaking of the soldiers and citizens. The worst case for NATO is US withdrawal and explicit or tacit support of NATO enemies. Some soldiers would blindly follow orders to march on Europe, but we can't even win a war against Iran right now so I'm not sure how much Europe has to worry about a US invasion. Canada, maybe, but that's probably even more unpopular in the US than invading Europe.

And it'd also be the end, economically, for the US. We'd be hosed, that isn't to say current leadership wouldn't try and end up fucking us all over, but the effect would be another loss for the US.
