I agree that what happened in the Phillipines over a century ago was utterly wrong. However, you cannot "extrapolate" that to confirm your view of "America's aggression"

With our military in the state it is in right now, we could invade, occupy, and dominate literally any country on the planet. We're not doing that.

I'd also caution you to note that many of the wars we've fought in were to stem the red tide of communism. It's easy to argue now, with the fall of the USSR, that it was pointless and bloody, but I personally believe that fighting those bloody wars caused the world to end up better than it would have had the kind of communism in the USSR, China, and other countries spread. Also keep the context in mind; the Cuban missile crisis is what fueled America's very real fears of communism coming to our shores.

I for one am glad we don't have a nation like DPRK on our doorstep to contend with.

Speaking of that, many of the wars we have fought were indeed good things. World War I. World War II. The Korean War (South Koreans of the right age group still thank us eternally), and ultimately, the demies of the USSR. Hell, it can be argued that we're even bringing China around (slowly), not through force, but through capitalism.

A good friend of mine is from China, and travels there on business on a regular basis; she says that the larger cities in China are quite capitalistic, and not that different from the US (if you stay out of the government's way).

In short, I believe that what we were fighting against, if spread, would have been far worse for America, and the world in general had we not fought it. Problem is, you're arguing against what did happen, and not what could have happened. I wonder if the kind of governments in China, USSR, and DPRK did spread, if you'd even be able to voice your opinion on the matter?
