CBS) One year after the declared end of major combat in Iraq, Americans have new doubts about the war and doubts about what the Bush Administration has said about it.

Just 32 percent, the lowest number ever, say Iraq was a threat that required immediate military action a year ago.

Less than half, 47 percent, now say the U.S. did the right thing taking military action in Iraq, the lowest support recorded in CBS News/New York Times Polls since the war began.

There are growing concerns about the long-term impact of the war. 41 percent now think the war increased the threat of terrorism against the U.S. 71 percent say the Administration’s policies have worsened the U.S.’s image in the Arab world.

The public’s assessments of the Bush Administration’s decision-making before (and after) the war are also negative.

Seven in ten don’t believe the Administration claims that the decision to go to war was made in March 2003, and say the Bush Administration had decided to go to war earlier than that.

61 percent believe the Administration did not try hard enough to reach a diplomatic solution before going to war in Iraq -- a reversal of the public’s belief last year during the war.
