You know, I've been racking my brain trying to remember when else in history a great military power launched a war of aggression against a neighboring country, failed to defeat it on the battlefield for years -- and then the leadership of another great power (which the aggressor had regarded as its archenemy until just yesterday!!) engaged in petty, sordid collusion with the aggressor, made a complete 180-degree turn, and began actively working to force its undefeated victim into capitulation and extinction as a nation.
I'm honestly trying to think of historical precedents -- but it seems that never before in the history of this world under the heavens has there been such a spectacular display of deranged idiocy.
