Americans are increasingly skeptical about whether the United States should thrust itself into conflicts overseas, according to the latest New York Times/CBS News Poll, but that reluctance does not extend to preventing Iran from obtaining a nuclear weapon.

After 12 years of war and amid signs of a sustainable economic recovery, nearly six in 10 people said the United States should not take a leading role among all other countries in trying to solve conflicts, the poll found, while only about a third said it should remain at the forefront.

On Iran, however, the same proportion of people — 58 percent — favored the United States taking military action to stop Iran from manufacturing a bomb, an action that President Obama has repeatedly warned the Iranian government is a “red line” for the United States.
