Bush: European missile defense system is a must

US President George W. Bush says he remains committed to building a missile defense system in Europe and will press Russian President Vladimir Putin to drop his objections to the project. Bush says he is willing to cooperate with Putin on the plans that he says are not aimed at Russia and that he plans to make that point to the outgoing Russian leader when he meets with him this week. He says the system is needed to counter potential threats from the Middle East.
