The "neo-con train has already left the station", yet you want to carve up relatively free sovereign countries such as Taiwan, Ukraine and the Baltics.
You weren't being serious, were you?
Governments are not acts of nature, they have no inevitability. Rather, they are inventions of man, to serve a set of specific interests.
The US federal government was established to prevent illegal acts of force and fraud, occurring either domestically or from foreign threats. Our duty to any other country goes only as far as it serves to protect our national interest ie the safety of citizens.
Alliances, foreign entanglements, domestic spending programs, etc, are all artificial constructs that can be changed to suit the people for whom government serves.
Security agreements with countries like Taiwan are inventions to enrich those who would benefit from conflict. With your surprise at my position, I'm assuming you've got something at stake?
