One year after Obama's anti-nuclear speech at the Prague Castle, the Russians and Americans agreed to sign a new nuclear treaty in Prague at the beginning of April 2010.
You won't find a city that is, from a long-term viewpoint. more accurately in the political middle between Russia and America than Prague. More precisely, you will find one: Pilsen which was liberated by the U.S. army unlike most of the country that was taken by the Red Army.
But they probably don't know Pilsen, so what can we do about it. ;-) Clearly, Prague was favored by the Americans as their attempt to calm down the dissatisfaction from Obama's broken missile defense pact with Poland and Czechia. President Klaus has already agreed with the choice, too.
Assuming that he will convince Obama to ultimately renounce the global warming hysteria, there exists no good reason to disagree. :-)
