You can't say that the second Gulf War is a loss, because neither has it been finished, despite what W says, nor has it failed all of its objectives. While WMDs were not found (we totally should know that it is not the reason at all), Saddam was still captured (also not a valid reason, unless revenge suits you).

Honestly, do you think that the new Iraqi government will stand more than a few years? We learned this from the Articles of Confederation, that we did.

Yeah, I know that sounds incredibly one sided and patriotic, and W-like, but it's the truth. It doesn't matter how far off or esoteric the objective is, but if it is fulfilled, it is a point for contention. If Korea is a half-victory, then it is also a draw, and assists are still wins, as whoever is involved wins by technicality.

And, who in their right mind would consider 1812 a victory?
