I think this is just another of their fvvk-ups like Vietnam, Iraq II, Afghanistan, Syria, etc. They thought they were going to cause Putin to lose face, the Russians turn against him, and Russia break-up. So far, I don't see any proof that's happening. Our government hasn't given us KIA estimates for the AFU. Open sources claim Russia is firing about 10x as many shells at the Ukrainians as the Ukrainians are at them. Meanwhile, the Ukraine is being destroyed and its people fleeing. Wicked.

Who cares what you think?
