Well Mish noticed:
Seriously, what vital national interest of the USA qua USA is threatened if Russia has a big influence in Syria? Or if Iran is a big player in its corner of the world? Or if Venezuela has a somewhat socialist government? Or if China polices trade going in and out of China in the South China Sea? Etc etc.Hypothetically, we bring all the troops home. What happens? Does anyone believe that Russia starts the tanks rolling west until they are in Portugal? Does anyone think China will build an invasion fleet? Iran does something horrible? Will Venezuela start running an efficeint non-kleptocracy?
The Neutralist, waiting for an answer since 2008. Actually, since the Carter administration.
