In addition to being an ethnic conflict, the Sri Lankan civil war is a religious one: most Sinhalese are Buddhist, while most Tamils are Hindu. [link]Obviously Obama reads the Newsweek. Heh. But seriously, let's rest it. Sri Lankan conflict is many things, what it's not is a religious conflict. The fact that most Sinhalese are Buddhist and most Tamils are Hindu (and all Mulims are well, muslims) doesn't mean that the conflict is drawn along those lines. That's like saying that in a war with say, the Americans and Japanese was a conflict between short people and tall people.
Other than that, the article is well worth a read.
