President George W. Bush said Tuesday that plans for a US-led missile defense system in Europe is urgently needed to counter an emerging threat of attack by Iran.
"If (Iran) chooses to do so, and the international community does not take steps to prevent it, it is possible Iran could have this capability," Bush said. "And we need to take it seriously - now."
Bush's latest warning about Iran's nuclear ambitions came in a broad defense of his security policies at the National Defense University. He said intelligence estimates show that Iran could have the capability to strike the United States and many European allies by 2015.
