The US, as most american countries did, gave space and hope to thousands of europeans. That was one good thing. They were probably the first country to try and practice modern age democracy. That's another good thing. They do tend to put their foot in their mouth, but there's always someone who acknowleges the fact and apologises for it. They actually helped us during both World Wars and they even fed us after WWII. They have wonderful writers, great poets, wonderful musicians. They sometimes seem strange to european eyes, but that's what usualy happens when children grow - the parents find them strange, but still love them. (Sorry if my english looks strange...)
