John McCain responds to a question [1] by ABC’s Charlie Gibson on whether Israel would be “justified” in carrying out an attack against Iran in light of its recent missile tests:

GIBSON: Would a strike by Israel be justified and what would you say to the Israelis?

MCCAIN: I can’t know whether a strike would be justified because I don’t know the progress or the significance or the nature of the threat. I know the threat is growing because of the continued development of nuclear weapons.

McCain’s awkward reply asserts that while he doesn’t know the “progress” or “nature” of the threat, he somehow knows that Iran is developing nuclear weapons — despite the overwhelming evidence to the contrary from the IAEA and the latest US intelligence reports.
