It is nice to hear what the US could all do,
but here we are in year 2 of a full on attack on Ukraine and International law.
Personally i don't believe Russia will attack Nato, but i'm not sure if the US will go full in for Taiwan.
The US seems very divided over Russia, but I think a Chinese invasion of Taiwan would unite politicians real quick. Both because it's vital economically, and because China is pretty much its arch nemesis.
