Bachmann: US Must Fight Iran Aggression, Quest for Nuclear Weapon

The United States should use all its resources to combat Iran's "tremendous acts of aggression" against Americans, Republican presidential candidate Michele Bachmann said today on ABC's "This Week."

The fundamental problem in the Middle East is "an Iran seeking to gain a nuclear weapon," the Minnesota congresswoman said.

"This will change the course of history once that occurs," she said. "What I would do is take everything at our disposal to make sure that Iran does not have a nuclear weapon. If there's anything that we have learned over the course of history, it is that, when a mad man speaks, we should listen."

President Barack Obama made the wrong decision to take out Libyan leader Moammar Gadhafi because the United States has no vital interest in the country, Bachmann said.

"That is the precursor for the United States' involvement in another nation's affairs," she said. "Now, we have a mess in Libya."

On the home front, Bachmann said Americans remain at risk because "the United States government has failed to secure our borders."

"Within one year of being in office, I would build the fence that's so necessary on our border."
