From the WaPo:
An assessment by U.S. spy agencies concludes that Iran is prepared to launch terrorist attacks inside the United States, highlighting new risks as the Obama administration escalates pressure on Tehran to halt its alleged pursuit of an atomic bomb.
In congressional testimony Tuesday, U.S. intelligence officials indicated that Iran has crossed a threshold in its adversarial relationship with the United States. While Iran has long been linked to attacks on American targets overseas, U.S. officials said they see troubling significance in Tehran's alleged role in a plot to assassinate the Saudi ambassador in Washington last year.
U.S. officials said they have seen no intelligence to indicate that Iran is actively plotting attacks on U.S. soil. But Director of National Intelligence James R. Clapper Jr. said the thwarted plot shows that some Iranian officials probably including Supreme Leader Ali Khamenei have changed their calculus and are now more willing to conduct an attack in the United States in response to real or perceived U.S. actions that threaten the regime.
The warning about Iran's more aggressive stance was included in written testimony that Clapper submitted to Congress on Tuesday as part of the intelligence community's annual assessment of the nation's most serious security threats.
A clash of cultures is coming, sooner or later. The argument really boils down to whether we deal with it now to minimize casualties or deal with it down the road when casualties may be catastrophic.
I do not envy those charged with making the decision.
