Prof. Thornton says the U.S. needs to show Europe some tough love, with particular regard to military matters. For instance, today the U.S. plays the necessary role of global policeman, but in terms of the security provided by the U.S., Europe is getting a free ride. This needs to end. Says Thornton, “We need to say to Europe: You guys are rich. You wanna be a big, important player? Spend the money on the military and then we’ll deal with you.”
