What expansion? The last two countries joined as result of Russian aggression. The ones before joined because they themselves had experienced that only the membership in a strong alliance can potentially safe them from annexation (Estonia, Lithuania, Latvia, Poland [the last after a deal with literally Hitler]). And once again tell me, why would anyone be afraid of a defensive alliance growing when you don’t intend to invade said countries?
Don’t want to invade your neighbour? Then their NATo-membership is not a problem, hell how about trying to join yourselves?
Wait are you implying Germany is the muzzle? Fuck good thing it’s pointed toward CZ and I am loving in northern Germany. I mean probably not the nicest experience to have a stray shot experience with a nuke
