We notice that through changes of administration
the war in Afghanistan goes on. The war in Vietnam
did too. Military interventions by the USA overseas
is no monopoly of either party.
To force the commies to send arms and money to countries that would never be able to repay, thus bankrupting communist countries.
That would be the right basic idea. Keep any anti US
coalition weak and disorganized.
The USA does self interest first; they are often inept and
not very subtle.
But, the world does revolve around the US, like it or not.
No preferable alternative is anywhere
near the horizon.
