Good read on President Obama's "gestures":
We must keep in mind the fact that Obama is not a yokel and that the State Department is there to prevent an ill-informed president from unnecessarily stepping on toes. What happened last Thursday was a deliberate gesture. It was aimed at our allies in eastern Europe and at Russia, and it was recognized as such in Poland, the Czech Republic, and Russia. Vladimir Putin spoke of Obama's decision as a courageous act. Our friends in eastern Europe would not have used that adjective. A signal has been given, and they know the meaning.
