We have a treaty to defend Taiwan? Seriously asking because I wasn’t aware.
Yea we do, but American guvmint has broken dozens of such treaties. Just ask the Native American tribes.
I stand corrected: we don't have a treaty as such, not since the formal recognition of the Communist Chinese Government in the late '70s.
What we have instead is the Taiwan Relations Act and other subsequent legislation which provides us the cover to supply Taiwan with defensive armaments and kind of weasel-words around whether we'd join the fight if they were attacked.
The idea that the US would step in is the only thing that has kept Taiwan out of Chinese Communist hands all these years.
