Ukraine's founding document, the 'Declaration of State Sovereignty of Ukraine', Article IX states:

   “The Ukrainian SSR (Soviet Socialist Republic) solemnly proclaims its intention to become a permanently neutral state in the future, one that does not participate in military alliances and adheres to the three non-nuclear principles: not to receive nuclear weapons, not to manufacture or acquire such weapons.” 

Thus, the major Russian goal in Ukraine is to punish Ukraine for breaking its promise to be a neutral country that would never endanger Russian security (a commitment that was also guaranteed by the Ukrainian constitution till pro-western Ukrainian leaders captured power undemocratically). This has been done by invading Ukraine, annexing Crimea and parts of Eastern Ukraine (to provide a land corridor to Crimea). (Crimea has Russia's only warm-water port and allows it to extend its influence to other neighbouring regions. NATO access to it would have crippled Russian Navy and Russian geopolitical strategies). Ofcourse, this war is illegal - but for superpowers, might has always been right. This goal of breaking up Ukraine to punish it has been nearly achieved as Russia has already captured 20% of their territory (Crimea + nearly all of Eastern Ukraine). Their secondary goal now is to prevent Ukraine from having a large army, joining NATO and ensuring Russia gets back its foreign reserves from the west (or capture more Ukranian territory, in lieu of it, if the west decides to keep their money).

Ukraine has neither the money, the manpower or the weaponry to prevent this unless NATO or EU joins the war (which it will not do so).

The major goals of the western superpowers (America, France and UK) was to ensure that Russia does not develop good political and economical relations with Europe as then Russia would compete in their Spheres of Influence in Europe. The Anglo-Americans especially needed Russia as a villain because without Russia as an enemy, NATO becomes irrelevant. Indeed, if European relations with Russia improved to the point of economic and military alliance, the possibility of a European army, with Russia in it, would have been a grave threat to the US. Already, American oil and gas industry were feeling the pinch of competing with Russia in Europe. Dangling NATO membership (which the west knew would never realistically happen because of Russian opposition) and engineering a civil war in Ukraine through the pro-western and pro-Russian Ukrainian leaders ensured Russia was sufficiently provoked to attack Ukraine. Russia can now be vilified and the current and next generation of Europeans will grow up hating Russia. This "generational hatred" thus sabotages any possibilities of the ties improving between Europe and Russia for the next few decades. Using the war, they have now been able to sway Sweden and Finland to give up neutrality and join NATO, which was another major goal of theirs - with Sweden and Finland in NATO, the Arctic Council is now fully NATO dominated, against Russia. This now makes it easier to curtail Russia's influence and vision for the Arctic region, where Russia is planning to build a new maritime route that would challenge the maritime powers of the west (mainly the US). Russia's Arctic vision (The Great Game in the Arctic: Why the region is the next flashpoint between superpowers - https://archive.md/sJ0fj ) is why Trump (and the US, in general) is so obsessed with Greenland. Other secondary goals including capturing Ukraine agricultural economy etc.

Russia and western superpowers have always known that the end result would always be a divided Ukraine.

However my point is that EU is bankrolling Ukraine and keeping it in the fight see 90 Billion EUR loan to Ukraine few days ago. Pretending that Russia does not need to negotiate with EU because EU does not have military branch yet is just being arrogant and stupid.
