Isn't Obama supposed to have a more sensitive foreign policy?

So on the 70th anniversary of the Soviet invasion of Poland, Obama has announced he is dumping the missile shield agreement with the Czech Republic and Poland. Wasn't Obama supposed to embody a kindler, gentler foreign policy? In order to not understand the implications of throwing Poland under the bus on this day is unbelievable. This is just more evidence that he and his staff has no knowledge of history (his lack of knowledge of economics is demonstrated by his domestic policies). People kept saying in 2008 how smart the guy is but I never really bought it, given his completely devoid of reality positions. He really does act like a complete schmuck. I'd like him to explain when throwing your allies under the bus has ever paid off? He has now done so with Israel, Honduras, Poland, and the Czech Republic. Columbia and Georgia are probably next. Remember the last time we had a President like this? It was Carter and he let our staunchest ally in the muslim world, Iran, fall, and turn into our greatest enemy of the last 20 years. Foreign policy mistakes are very hard to undo and can have very long lasting and deadly implications. It's a real tragedy.
