He sure as hell wasn't going to win one of those by adopting a George W. Bush/Dick Cheney/John McCain/Lindsey Graham/John Bolton foreign policy.
Dude, how did we achieve peace with Venezuala? With a focused and devistating military strike against a tyrannical regime. Why do you think that Venezuelan lady gave Trump her Peace Prize? Why do you think Trump is practically a God among Venezuelan expats? He liberated them from a violent oppressive government and he made our own country more safe and secure in the process. No more Russian/Chinese proxy on our doorstep.
THAT’S how you spread peace - with negotiation if possible, and with action if necessary.
