Mitt Romney campaigned in Iowa on Saturday
CHEROKEE, Iowa (CNN) - Adding to his comments on the release of a new Osama bin Laden tape, Republican presidential candidate Mitt Romney said Saturday that the Al Qaeda leader is "almost incomprehensible for people of this country to understand, how someone can be so deluded."
At an event in rural Iowa, Romney told reporters, "I think when he makes tapes like this it hurts his effort, doesn't help it."
The former Massachusetts governor also said the United States is facing "unusual times" and undergoing "challenges."
"They're so significant, these challenges, that I'm convinced America is going to have to change course in some respect," Romney said.
He cited the U.S. Revolutionary War and Civil War as other examples of times when the nation has changed it's path.
"There have been some changes in Americas history. One of those I think is occurring now, because of the forces that are going to be upon us. One of those forces is the radical Jihadist movement around the world, trying to bring down civilization and us in particular."
Romney also touched on the subject of Iran.
"I want to indict [Iranian President Mahmoud] Ahmadinejad for incitation to genocide. There is a genocide convention that calls what he has been saying as a violation of that convention."
Romney said he wants to make it clear to the people of Iran that nuclear proliferation is the wrong answer, and he said this message should be delivered to a specific group of the population.
"I think they have 75,000 bloggers in Iran, people who are on the internet.
I want to communicate to them that becoming a nuclear nation is not a source of pride, it's a source of peril."
He continued, "It's a very dangerous thing to become a nuclear nation. They need to understand these things. I hope that will convince them that they need to pull back their nuclear ambition."
