Eastern Europe: USA ditching missile defense.
Poland and the Czechs are members of NATO, so their security really isn't a concern. The message sent here is to Ukrain and Georgia...your on your own. Figure out a way to deal with Russia, because the United States under the Obama administration is not going to stand up to them on your behalf.
From a technical and monetary standpoint, it might have been a logical decision (though with Iran having the ability to launch a satilite in orbit that can be disputed), but from a forgien policy position, it was a complete disaster. Obama is not a world player...Putin is.
Why should any eastern European country form alliances with the United States now, knowing that if Russia barks, the US will back down?
