Boehner said it would be "a mistake of historic proportions" to retreat from Iraq. He added that Democrats were wrong to think that the military surge wouldn't work.
"If we lose Iraq we lose the region and we make it far more dangerous for Israel to exist," he said.
Boehner then turned to the specific dangers that Iran presents.
"If we do not stop Iran from devleoping nuclear weapons, we will lose Israel, and if we do not take seriously the words and attentions of Islamic militants, we lose Israel," he said.
His Democratic counterpart, House Speaker Nancy Pelosi (Calif.), is about to take the stage.
