By a 45% to 32% margin, more Americans believe that the best way to reduce the threat of terrorist attacks on the U.S. is to decrease, not increase, America’s military presence overseas. This is a stark reversal from the public’s position on the first anniversary of the Sept. 11 attacks. In the summer of 2002, before serious public discussion of removing Saddam Hussein from power had begun, nearly half (48%) said that the best way to reduce terrorism was to increase our military involvement overseas, while just 29% said less involvement would make us safer. ~Pew Research Center

Of course, the biggest changes have taken place among Democrats and independents.  Republicans remain more committed to interventionism, but they are less committed than they were four years ago:

The views of Republicans on this issue have been more stable. The percentage of Republicans saying an increasingly robust overseas military U.S. presence will be more effective in countering terrorism has fallen from 58% to 45% over the past four years. However, just 30% of Republicans say a smaller overseas military presence would be more effective, up only modestly from 2002 (22%).

One third vs. one half isn’t what we’d like to see, but it’s a start.  In any case, Iraq has severly weakened the appeal of interventionism across the board, though obviously the opposition party and those not attached to either party would naturally be more inclined to turn away from the kind of foreign policy currently on offer.  The main question now is how to translate this newfound opposition to intervention into practical opposition to the efforts to precipitate a war with Iran.
