If you can remember Hungary in the 50’s or Czech rebellion of the 60’s–then you can understand why those people in Eastern Europe are worried.

Signing a missile-defense deal with its good friend the United States has earned Poland nothing less than the threat of nuclear attack from Russia — a threat that might not sound so empty these days, given Moscow’s bloody battle with Georgia.

That conflict has plunged Europe into crisis, sending waves of jitters through Poland and other eastern nations, once-occupied parts of a Soviet empire that some fear Russia may want to reconstruct. Moscow’s actions have also succeeded in driving deeper the wedge between Europe’s East and West.

Ukraine and Moldova are worried that they could be Russia’s next targets. The Czech Republic, on the eve of the 40th anniversary of a Soviet invasion that crushed the Prague Spring reform movement, is fretting about history repeating itself. Many Eastern European nations, Poland chief among them, are eager to find safe haven, and have turned to Washington for guidance and reassurance and partnership.

But the fact that the distracted and overly stretched Bush administration took little concrete action to protect Georgia from Russia’s wrath must also give pause to nations that would throw their lot completely with the U.S. Is the strategic alliance that many Eastern European countries have been building with the U.S. since the fall of communism nearly two decades ago still worth the risks?
