In the first and second Chechen wars, the Russians killed at least 100,000 people, most of them civilians, and they used gas.
We didn't bomb Moscow.
The Chinese killed at least 500,000 Tibetans, maybe as many as a million, almost all of them civilians (though they preferred the more old-fashioned method of simply lining people up and machine gunning them or herding people into buildings and then blowing them up, so perhaps that doesn't get us as upset.)
We didn't bomb Beijing.
The list could go on and on.
I can't believe that I'm agreeing with Newt about something, but he's correct on this one: stay out of their civil war, selective U.S. intervention is ludicrously misguided, it will do nothing and prove nothing.
All that is needed to make a happy life is within yourself, in your way of thinking. -Marcus Aurelius
