What evidence do you have to back your claim?
Whether the war can be 'won' or not is irrelevant. What matters is the perception of Americans, they want to win, regardless of the situation.This isn't true based on many polls I've seen. But more importantly, it's not a war that can be won. Vietnam couldn't be won and a 'war on terrorism' definately can't be won. Stop buying the advertisements of the State Department of Propaganda - you may actually learn a thing or two by keeping your mouth shut and listening.
Actually, the high energy prices are a direct result of environmental regulations (making energy production more expensive) and the declining dollar (which is the result of the failed policies of the Federal Reserve). I suggest tossing the tin foil hat aside and studying some economics.The economic recession the US is in is directly linked to the war and the resources it's costing the country to continue the policy over there. So you're missing the "big picture" on that one too.
