NATO and America still seem to hold to the nuclear doctrine of MAD, mutually Assured Destruction. That idea is based upon both sides in the nuclear confrontation having roughly equal destructive weapons. However, the Russia’s now have various nuclear weapons that the US, supposedly does not, such as the Poseidon nuclear sub, capable of sitting on a coastline at the bottom of the sea, to be remote detonated. And, as noted by the Americsan.thinert.com, what is ignored here is that Russia and china have the policy of “escalate to de-escalate,” with Europe being a test case, being easily annihilated to teach America they mean business. Perhaps the UK will be buried under radioactive water. Neither side seems able to back down now, so a hard ending seems inevitable.
