I wouldn’t be so worried about Obama attempting to initiate a nuclear strike. I am terrified that if we were launched upon by Iran, Obama might refuse to retaliate.
Even so...if Iran DID launch against us and we KNEW it was them, and Obama did nothing, wouldn't the American public be crying out for his head? That might be the trigger that causes the American people to rise up en masse and DO something more than cast votes in an election.
