What you mean to say is that Neo-Soviet Russia kills Christians in Sudan by arming and supporting Bashir and refusing any international action just like in Syria.
But have you ever piped up about intervention in Sudan? I agree we should intervene in Sudan - destroy the foundations of Sunni Arab power there and put non-Muslims in charge, for a change. I think if we're going to put the air force to work, we should do Arc Light strikes over Iranian nuclear installations after destroying their air defenses. This stuff about Syria being an Iranian proxy is nuts. Napoleon once said "when you set out to take Vienna, take Vienna". Iran is the problem, so we should hit Iran. Syria's relationship to Iran is similar to Thailand's (as well as Burma's, India's and Indonesia's) cozy relationship with Japan during WWII - it's strictly a marriage of convenience rather than of any kind of ideological kinship.
No offense, but I'm seriously starting to suspect that you're either married to a Sunni or have a really good Sunni friend. SunkenCiv is from Michigan, so I suspect he's more or less in the same boat.
