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

A base becomes useless pretty quickly if it can't be resupplied, I suspect there is enough hostile AA around it to ensure that.

Unless the base is completely dependent on host country to supply electricity water and gas + it is inland so it is not possible to supply it in any other way than through air, which can be easily intercepted.

For a moment I agreed: Yes, a flamethrower-wielding Till Lindemann with a bare vulva backdrop would scare the shit out of those troops.

The fact that the Lindemann doctrine is back on the table speaks volumes about the state of affairs.

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.
