Republican senator and former US presidential candidate John McCain told Fox News on Monday that a missile defense system scrapped by the Obama administration should be brought back in response to Russia's invasion of Crimea. The senator joined other Republicans, including former vice president Dick Cheney, in criticising the American president, saying for example that Mr Obama had completely "misread" Russian leader Vladimir Putin. Missile defense was a project strongly pursued by the administration of George W. Bush. Originally, a rocket system was planned in Poland and an early warning radar in the Czech Republic. Czech Foreign Minister Lubomír Zaorálek responded to the comments by saying such a system would not have changed anything in the current crisis.
