apple: They ignored Cambodia, they ignored Rwanda, they appeased Iraq, they appease North Korea, and they appease China, they appease Syria, they appease Cuba. Whenever action is proposed to take steps to end human rights violations in such countries, they can only protest that it will cost lives. However, they fail to look at the bigger picture.
Couldn’t you say the same sort of thing about conservatives, using a different set of human rights violators? Conservatives appease Colombia, they appeased Guatemala, they appease Saudi Arabia, etc., turning a blind eye to rights violations for the sake of keeping in power a government (however brutal) that’s sympathetic to US interests. If conservatives are more ready to go to war than liberals, that doesn’t necessarily mean that they’re more committed to human rights.
yet liberals seem to be unable to see beyond their rabid “peace at any cost” position
I think you’re confusing liberals with pacifists. The majority of liberals don’t actually espouse the absolutist-pacifist principle of “peace at any cost”. Most liberals, for example, thought the post-9/11 invasion of Afghanistan was necessary, and many supported intervention in the former Yugoslavia.
while [war] will cost lives in the short run, the long term effects will far outweigh the short term losses.
That’s the only real justification for fighting a war (and you also seem to be somewhat confusing starting a war with sending peacekeeping forces to avert a war). Unfortunately, it’s damned difficult to predict when or how a military intervention will actually make people better off in the long term.
You are right that the world in general definitely needs to figure out an international policy for defending human rights in other people’s countries. At present, we are wrestling with the principle that you shouldn’t invade or attack another sovereign nation in order to save its people from their own government. But that principle leaves us in the position of bystanders while innocent people are butchered—“us” including anti-entanglement conservatives as well as anti-imperialist liberals.
This is not a problem with liberalism; this is a problem with the conflict between the comparatively recent concepts of human rights and national sovereignty. It’s going to take all of us, conservatives and liberals alike, to work out a just solution to it.
