Clinton: Gravest U.S. threat is terrorists who get WMDs.

Senator Hillary Clinton said Monday that America's gravest threat is that terrorists will obtain weapons of mass destruction.

Clinton was in Washington on Tuesday testifying before members of a Senate panel who will recommend if she should be the next U.S. Secretary of State under president-elect Barack Obama.

The gravest threat that America faces is the danger that weapons of mass destruction will fall into the hands of terrorists, she said, according to prepared remarks of her opening statement before Senators in Washington.

To ensure our future security, we must curb the biological, chemical, or cyber – while we take the lead in working with others to reduce current nuclear stockpiles and prevent the development and use of dangerous new weaponry.

The administration would work with Russia to extend monitoring and verification provisions in a treaty set to end this year and work for further reductions this year.

We will also work with Russia to take U.S. and Russian missiles off hair-trigger alert, act with urgency to prevent proliferation in North Korea and Iran, secure loose nuclear weapons and materials, and shut down the market for selling them.
