The unmanned victory

I’m trying to figure this out.

According to poll numbers, more people are supportive of the US being in Iraq. Also, people think that the US can win the war, but won’t. They also think that we should withdraw troops.

Does this mean people think we will win if we withdraw troops? How does that work?

(I know it’s logical fallacy to draw these kind of conclusions from poll results. I’m just being silly.)
