My understanding was that we could no longer wait for a threat to become imminent:
Iran is prepared to launch attacks using long-range missiles, secret commando units, and terrorist allies planted around the globe in retaliation for any strike on the country's nuclear facilities, according to new US intelligence assessments and military specialists.
Let me make sure I understand this, we either allow Iran to get a nuclear weapon their president has shown a giddy desire to use to create havoc and kill many, many people, or they will create havoc and kill many, many people.
''When the Americans or Israelis are thinking about [military force], I hope they will sit down and think about everything the ayatollahs could do to make our lives miserable and what we will do to discourage them," said John Pike, director of the think tank GlobalSecurity.org, referring to Iran's religious leaders. ''There could be a cycle of escalation."
I gather a cycle of subjugation is preferrable then. Apparently, the old "you've got a nice country there, I'd hate to see anything bad happen to it" gambit still works.
