Why are we still embroiled in 2 wars

Now that the era of Peace and Loving has dawned, I see no reason we should still be fighting far away. Don't these people read the news? My personal favorite news item today is this one from yahoo:

WASHINGTON – The U.S. military in Iraq is abandoning — deliberately and with little public notice — a centerpiece of the widely acclaimed strategy it adopted nearly two years ago to turn the tide against the insurgency. It is moving American troops farther from the people they are trying to protect.

Yes, by all means let us portray it that way, lest someone get the idea we are winning.
