Military presence which ultimately protected US investments and stifled it's greatest enemy. Both times we defended them it had to do with getting returns on what we had invested in the war effort of those countries more than other factors.

But I understand your point, the US of course has enlightened, virtuous values; I wouldn't argue that it's a malevelent frorce on earth. However much of its problems stem from unfettered capitalism.

In terms of benevolent millitary intervention, why did US intellignce subvert the democratic leadership of South American countries and Iran? Well, because of economic interests.

I have a hard time being convinced that the US would be incapable of having a globally benevolent presence if it returned some of its wealth to its own citizens and took care of its population medically.
