Good afternoon Brits,it is all so confusing to me?

In WW 2 we yanks should have rush troops to your aid sooner than was bad that we took so long to get involved in your war, South Korea and Vietnam that was bad we should have let north Korea invade the south as they did in Vietnam, Falklands it was bad we did not join you in your rush to war. Mr Reagan attacking Libya was bad. Mr Reagan calling for the destruction of the evil empire that was bad. The first gulf war when Iraq invaded Kuwait,that was good.Releasing the Lockerbie bomber was good .Mr Obama getting the ball rolling on your call for war against Libya that was good, Mr Obama pulling back and letting y'all run the show that was weak, Please explain
