Speaking on NBC's "Meet the Press," Netanyahu said he would not criticize Obama, who has been accused of being too soft in his defense of protesters in Iran who have taken to the streets of Tehran in the wake of a disputed election.
"I know President Obama wants the people of Iran to be free," Netanyahu said in the interview.
Netanyahu said that those who have taken to the streets are showing "an incredible act of courage."
"You see a regime that represses its own people and spreads terror far and wide," he said. "It is a regime whose real nature has been unmasked and it's been unmasked by an incredible act of courage by Iran's citizens. ... You see the Iranian lack of democracy at work."
Obama used the most frank language yet on Saturday when he called on the government to "stop all violent and unjust actions" against its people.
"The universal rights to assembly and free speech must be respected, and the United States stands with all who seek to exercise those rights," Obama said in a statement.
Sen. John McCain, one of the president's most vocal critics on Iran, pushed a strongly worded bill through Congress condemning violence against Iranian protesters, in what some say was a response to Obama.
On CBS' "Face the Nation" on Sunday, McCain praised Obama's latest statement on Iran.
"I appreciate the statement that he made yesterday that was far stronger," he said. "And I think we need to continue to send that message."
