Major American Wars-Losses, Wins, Ties, and What Qualifies.

While the Iraq War was over-expensive, I don't see it as one that can be put in the loss column.  If Iraq was a loss, then so was the War of 1812.  The US failed to achieve any of its war aims, had its capitol burned and looted, and nearly triggered an internal civil war.  If the British hadn't tried and failed in the winter of 1814-5 to take New Orleans, it's entirely possible that we'd have seen the breakup of the Union

Would any of the Indian Wars be large enough to count? Could those all be lumped together?

The Seminole Wars were probably the most significant of the Indian Wars not associated with some other conflict post-Independence.
