Who are you to suggest their lives had no meaning because they happened to be on the "wrong side"?
Heavens no. NVR makes a good point: that at one point in history, US allies were US enemies, and this is true of other countries. And while taking into consideration that we have members here of all nations, every nation has had it's battles, every nation maintains military might to the best of its ability and budget for a reason--sometimes that reason is for it's own protection and it's own interests and sometimes for others' lives and interests.
Without this fact, there'd still be Jews in concentration camps in Europe, every Pacific Island would be 'enemy territory' including Hawaii, we would have shitty American made TVs & VCRs and Toyota wouldn't have the largest truck plant in the USA. Really, does anyone here NOT think that USA-led UN forces should have 'restructured' Rwanda when 100's of thousands were being slaughtered in the 90's? In just 5 months up to 600,000 were murdered, shouldn't 'we', a Superpower, have acted? Would that have offended anyone? Yet, the acting goverment used its own Rwandan military to organize and carry out this mess.
I don't believe that anyone here is naive enough to believe that there's never been an immoral or criminal act committed by those on a military offensive.
