If the enemy already has a base inside your country, you're at a severe disadvantage... it's like realizing you've been cannon rushed in starcraft

I can see how it all becomes deliberately muddied these days but there still is a fundamental difference between defense vs. hostile action. And it’s not necessary for defense to see anyone else as “enemy” either. Bees and other animals invade “my” territory and I may want them out and will extract them, but they are still not enemies.

Germany is deploying its troops to NATO protected land, Greenland. Something relatively acceptable.

Germany has also given more than most countries to defend Ukraine.[0] No foreign country has deployed their troops to Ukraine.

I genuinely do not understand your take.
