It's not in their interests to destroy us. It IS in their interests to create areas of destabilization and buffer zones of those unfriendly towards the West.
No. This is an error. What they have done is not in their interest and has already backfired on them badly. Russia's stupid and evil invasion of Georgia has destabilized the entire Caucasus and advanced the cause of ethnic separatism all over Russia itself. Russia's problems in the North Caucasus have only increased since Russia's genocidal invasion of Christian Georgia. Russia will pay for unleashing their pet Chechen muslim red army jihadists against Georgia. They never learned from Beslan. Beslan was blowback from when Russia supported Shamil Basayev's jihad against Georgian in Abkhazia in the early nineties. Now there will be more Beslans.
