Definitely not. For a variety of reasons that we needn't go into here.
Personally I wouldn't be putting a head on a spike. But there will come times when those that will, will. History tells us this.
It's always amusing to discuss alternative histories - especially with people that know their history. Because as you do more and more, you realise that there aren't "pivotal" moments in history. That's all bollocks dreamt up by simple people for simple people.
The reality is when change comes, it's as a result of preceding changes that make it inevitable, when you zoom out.
For example, the US was going to enter WW2 no matter what happened when. If it wasn't Japan in December 1941, it could have been Japan in 1942. Or Germany in 1943. There isn't a "history" in which America did not enter (or win) the war. "The Man In The High Castle" is a splendid paradigm of Dicks complex view of the world. But as a "what if" it's dead in the water.
Rome was always going to fall. So was Constantinople,. WW1 was always going to happen, no matter what happened to Archie Duke and his ostrich.
Whether things happen within our time, or are pushed out a few decades - maybe a century - won't change the fact that's where we are headed. And apparently, looking at the polling, where we want to be.
Funny old world, innit ?
