Former president George W. Bush says that President Obama “understands the threat” posed by Iran. “There is a certain reality to the world,” Bush said earlier today in a meeting with reporters. “The fundamental question is not whether the United States sees the threat; I think the United States does see the threat. You can’t be a strong ally of Israel without knowing the threat.”

“The question is do others see the threat,” Bush says.

Speaking more broadly about U.S. foreign policy, Bush notes that he remains “worried about isolationism.”
