There is no good reason for NATO to be expanding anyway. China is a bigger threat to Taiwan yet, the US will let Taiwan be gobbled up by China. Only a matter of time.
I do not know.
A lot Americans like isolationism for many years. That is at least half of the Republicans do. But US has been involved with all global conflicts since Cold War. Korean War, Vietnam War, Iraqi War, Afghanistan War, Syrian Civil War etc. But nothing is working. How many $BB we spent each year? How many American soldiers dies? We do not even have money to fix our broken bridges.
Yet, those army generals always like wars. Politicians like to be strong. But all civilians suffered and died. We fight just for the ideology. It is empty.
