Joseph Lieberman actually said...

U.S. policy, in short, should be to increase pressure on the Iranian government at a time when it finds itself an international pariah.

As many Congressional leaders have stated, we must negotiate with Iran from a position of strength.

Now is therefore not the time, in my judgment, for the United States to consider a military approach to this dilemma.

They should make a much greater effort to join in the international pressure on Iran to give up its nuclear ambitions.
