Are Nuclear Weapons the Single Biggest Threat to U.S. Security?

Obama is tamping down on nukes, but others urge caution.


President Obama and top officials from 47 other countries have convened in Washington, D.C., today for the Nuclear Security Summit, to halt the spread of nuclear weapons and to keep them out of the hands of terrorists. No new sweeping changes in foreign policy are expected to emerge from the meetings, but Obama says he and other world leaders share a "sense of urgency." The president has also said that the single biggest threat to U.S. security is the possibility of a terrorist organization obtaining a nuclear weapon. Some officials urge caution against moving too rashly in adopting new policies or sanctions toward other countries. Appearing on ABC's Good Morning America, Russian President Dmitry Medvedev, for instance, said that Iran's nuclear program must be watched closely, but warned that sanctions might "lead to humanitarian catastrophe, where the whole Iranian community would start to hate the whole world."

What do you think? How prudent—or aggressive—should President Obama and other world leaders be in the stance they take toward other nations' nuclear programs? Take our poll and post your thoughts below.

This poll is now closed, but the debate continues in the comments section.
