Moscow angered by Czech-US missile defense treaty

There is heightened tension between the United States and Russia following the signing of a missile defense treaty between Washington and Prague on Tuesday. The agreement opens the way for the deployment of a US tracking radar on Czech soil. Russian President Dmitry Medvedev said his country was “extremely upset” by this development and was considering retaliatory action. Speaking at a meeting of Group of Eight leaders in Japan President Medvedev said that although Moscow considered these plans a threat to its security it would act “without hysteria” and remain open to talks.
