(CNN) - Israeli Prime Minister Benjamin Netanyahu has key billing in a new ad running in Florida.
The spot, produced by the independent group Secure America Now, shows Netanyahu voicing his concern about what he and other world leaders suspect is a nuclear program being pursued by Iran.
"The fact is that every day that passes, Iran gets closer and closer to nuclear bombs," he said.
"The world tells Israel, wait there's still time. And I say, wait for what? Wait until when?" he continued.
Netanyahu made the comments to reporters last Tuesday in Jerusalem shortly after Secretary of State Hillary Clinton said the United States would not be "setting deadlines" for Iran, though it would be "watching very carefully about what they do, because it’s always been more about their actions and their words." In an interview on CNN's "State of the Union" on Sunday, Netanyahu urged the United States to set a firm "red line" for Iran.
Secure America Now has so far bought $500,000 of television time over two weeks in the Florida markets of Miami, Fort Myers, and West Palm Beach, a source with knowledge of the group's plans told CNN.
The source said the group budgeted $1 million worth of time for the ad, but had not yet purchased the full amount.
Previous ads from the group have been critical of President Barack Obama.
In his "State of the Union" interview,, Netanyahu said that there are people who "are trying to draw me into the American election, and I'm not going to do that."
Regardless, he has become a figure in the election year back and forth between Obama and republican challenger Mitt Romney.
Sources told CNN recently that the White House had turned down an Israeli request for a meeting between Netanyahu and Obama while Netanyahu is in New York at a United Nations meeting, prompting Romney to say he "can't imagine ever saying no" to a meeting request from Netanyahu. The White House said no meeting request had been made, and within hours of the story breaking, Obama called the Israeli prime minister and said the two countries maintain "close cooperation on Iran and other security issues."
When Romney visited Israel on an international tour in July, Netanyahu had kind words to offer Romney, saying to the GOP candidate, "I couldn't agree with you more" on Romney's tough words for Iran.
