A better analogy -- and with more relevant lessons -- to the current situation would be the Phillippines occupation following the Span-American war. Domestic politics were split just as they are today, with both candidates for President in 1900 running in support of the previous war but deeply split over how to handle "the peace." This cartoon is a primer for ya:
"Take your choice--Do you want a man who, having raised the stars and stripes on our new possessions, ... or a man who will cut down "Old Glory"?
That's Republican McKinley raising the flag, and Dim W.J. Bryan chopping at the mast. A political cartoon, but accurate nonetheless. You will find all kinds of parallels between these conflicts, especially as regards muslim insurgency, domestic U.S. backbiting, and a long, steady and eventually successful political process in the occupied land.
This comparison, often made by Max Boot, doesn't hold up. The Phillipine insurgency was different in an important way from the Iraq insurgency. Most notably, the Phillipine insurgents hardly had any guns and were generally armed with knives and machetes. They had disarmed themselves shortly before the U.S. occupation began. Iraq, by contrast, is awash in guns. Despite the lack of guns by the insurgents in the Phillipines, over 2,000 American troops died.
