The Czech Republic is withdrawing from U.S. missile defense plans out of frustration at its diminished role in a new U.S. plan, the Czech defense minister told The Associated Press Wednesday. The Bush administration first proposed stationing 10 interceptor missiles in Poland and an advanced radar in the Czech Republic, saying the system was aimed at blunting future missile threats from Iran. But Russia angrily objected and warned that it would station its own missiles close to Poland if the plan went through. In September 2009, the Obama administration shelved that plan and offered a new, reconfigured phased program with a smaller role for the Czechs, who were offered an early warning center that would gather and analyze information from satellites to detect missiles aimed at NATO territory.
