PollingPoint asked how you felt about threats to national security. Are we on the brink of a new nuclear age? Here’s what you said:

There was clear concern about the probability of a nuclear attack on the United States and an obvious partisan split: Republicans were more likely than Democrats to consider the probability of an attack high or very high.

At the present moment, what do you think is the probability of a nuclear attack on the United States?

Not surprisingly, terrorists and Al Qaeda were the most feared nuclear threats, with Iran a distant second.

Which entity do you think is most likely to attack the U.S. with nuclear weapons?

Respondents again revealed their partisan stripes when asked whether they would support U.S. military action against Iran.

Do you think military action should be taken by the United States if Iran continues its nuclear programs?
