"It was a festival of slights," the host of "The Daily Show" said, pointing out Netanyahu's statement that he was representing all Jews by criticizing the President's negotiations with Iran.
"I speak for all Jews! Including the ones who don't want me to! Because those Jews are wrong!" Stewart shouted.
The host focused on the part of Netanyahu's speech that claimed Iran has taken over Arab capitals such as Baghdad in Iraq.
"We have to act!" Stewart said. "Look how Iran has expanded its power since the fall of Saddam Hussein and the destabilization of the region!"
"I mean, what kind of idiot wouldn't have seen that coming in 2002—oh, shalom," Stewart said, turning to a clip of Netanyahu addressing Congress in the build up to the Iraq War.
"If you take out Saddam, Saddam's regime," Netanyahu said in 2002, "I guarantee you that it will have enormous positive reverberations on the region."
Netanyahu added at the time that an "implosion" of the Iraqi regime could very well bring the Iranian regime to its knees as well.
"Or the opposite," Stewart said.
