Let's look at the entire post-WW II era. NATO and Europe's freedom are a win. We won the Korean War in that South Korea is a free and prosperous ally today. The Vietnam War is less of a loss than it may seem in that it was won as a holding action that broke the Communist advance in Asia. And Vietnam today is on commercial good terms with the US and becoming an economic rival to China. We also won the larger Cold War, of course.
We won the First Gulf War, and time may yet show that we won the Iraq War, perhaps even the Afghan War, in spite of our ignominious last days there. We also won numerous brush fire wars and guerrilla actions. Columbia, for example, beat back its narco insurgency with US help. And I count Israel's survival as a free and prosperous American friend as a win.
