check out this rant by Donald Trump on Cavuto today
It's great when he said in regards to sending an aircraft carrier to protect South Korea that "they (SK) should pay for protection." That kinda sounds like he's not much of an interventionist. I think he's against the current wars as well so I guess that puts him slightly above the typical neocons.
But on the economic front, he sounds like an isolationist with the whole tax Chinese imports idea and thinking that the U.S. will gain more respect from the Chinese after that. It seems he's not afraid a trade war.
