While I am happy to agree that the US has, in the past, been more than ready to interfere in the politics of other countries, particularly if their ideology or their oil supplies were threatened, but in this instance the war is completely of Putin's making and a result of his delusive thinking. Since the ending of the Cold War the West has not interfered in Russia's affairs, nor has it threatened to attack it. In fact, it has bent over backwards to placate it and to tolerate outrages such as the annexation of the Crimea.
It is such a shame that Russia and the West could not have peaceably co-existed but it was never going to happen under Putin.
This isn't a thread I want to be involved in, either.
