With US troops?
Ukraine has a right to defend itself, but US troops are not deployed in Ukraine.
The Green Berets are the army’s spec ops that focus on training foreign fighters, specially chosen for things like foreign language proficiency. They’re not Rangers or general light infantry. Ideally they’re not really supposed to get into direct combat, as they’re rather time consuming and difficult to replace.
I would bet a whole bunch of money that we actually do have Green Berets present in Ukraine as well, though the only people that would know that for sure would be the US govt, the Ukrainians and probably Russian intelligence.
If the 101st Airborne gets deployed to Taiwan, then I’d be worried.
It doesn’t. The vast majority of countries recognize the PRC having sovereignty over Taiwan, as does the UN. There is no right to separatism or anything like that. Rather the PRC has the right to enforce their sovereignty. The US btw has no right to send to troops into China, that’s an act of war.
