How Sri Lanka defeated the LTTE

[CWOT]

I have a forthcoming essay in Joint Force Quarterly on the topic. Hadn't seen this thread, but the essay pretty much tracks Bill Moore's reasons above - the isolation of the LTTE politically, financially, and militarily played the decisive role, the military operation and tactics used were icing on the cake.

I saw a couple unsupported claims in newspaper articles about the use of paramilitaries and intelligence cooperation and isolation of the Tamil Diaspora to cut off their funding from transnational systems. But no one sources it, so I'm not sure if it is just general talk or a definitive strategy by the Sri Lankan government.

There is some good discussion about the Eastern Branch of LTTE breaking away from the north, but the COIN techniques used in Iraq don't really seem to emerge.

Has anyone seen any proof of these techniques?
