If your only prerequisites for declaring war are:

a) they have, or can someday have, weapons that they could in theory use against us; and

b) they don't like us;

then the list of countries you should invade is probably in the dozens and arguably larger than the list of countries you shouldn't invade.

Any country that attacks the US is committing national suicide. That's evident in the fact that no country has attacked you in 75 years. But you have invaded (or tried to invade in the case of Cuba), about a dozen countries in that same time, often without provocation or facing any direct threat to yourself (e.g., Vietnam, Granada, Iraq II). It's hypocritical therefore to point the finger at others as being out to cause mayhem when you're the most aggressive and destructive force in the world in recent history.
