(CNN) – For the second day in a row, presumptive GOP presidential nominee Mitt Romney labeled his rival weak on combating a nuclear Iran, saying President Barack Obama is more worried about Israel, an American ally, taking preventative military action than about Iran itself.
"This president has communicated in some respects that he might even be more worried about Israel taking direct military action than he is about Iran becoming nuclear," Romney said Sunday on CBS. "That's the opinion of some who watch this."

Romney made similar remarks Saturday, speaking via satellite to a conference of evangelical Christians in Washington.
Asked by a member of the audience at the Faith and Freedom Coalition conference how he would handle relations with Israel as president, Romney said, "I think by and large you can just look at the things the president's done and do the opposite."
He also used his line hitting Obama, saying: "He's almost sounded like he's more frightened that Israel might take military action than he's concerned that Iran might become nuclear."
The tough rhetoric from Romney drew a response from Obama's re-election team, which issued a statement listing important steps taken by the Obama administration to bolster relations with Israel while slamming the Republican candidate for attempting to "score cheap political points by distorting President Obama's record of support for Israel."
"Our relationship with Israel is too important for Gov. Romney to play politics with it," Obama campaign spokesman Ben LaBolt wrote.
In an interview with the Atlantic Monthly in March, Obama maintained that a nuclear Iran was "unacceptable," and said Iran and Israel understand that he isn't bluffing about his opposition to an Iranian nuclear weapon.
"I think that the Israeli government recognizes that, as president of the United States, I don't bluff," he said.
"I also don't, as a matter of sound policy, go around advertising exactly what our intentions are," Obama continued. "But I think both the Iranian and the Israeli governments recognize that, when the United States says it is unacceptable for Iran to have a nuclear weapon, we mean what we say."
Iranian officials have insisted their nuclear program is intended solely for peaceful purposes, though their statements have not persuaded officials in Washington and Jerusalem.
