But could any of the politicians or military officers mentioned on this thread have diffused the 1783 mutany of the Continental Army before it marched on the Continental Congress and overthrew them by giving a freaking speach that apparently wasn't all that good, then resigning? I'd put the odds somewhere less than 50-50. And if you get a civil-military balance that looks more like Latin America, for example, democratic consolidation gets a lot harder. Particularly given the already-present factionalization.
So you _could_ see a scenario where the Continental Congress--of whom the Continental Army already had a low opinion--actually hammers out a compromise with someone like Green standing in for Washington. But honestly, increasing factional discord followed by a Society of the Cincinnatti-style coup looks more likely to me.
I disagree. A mutiny? Definitely possible. "March on Philadelphia and bully the civilians into doing what we want?"
Washington might have been able to defuse that easily, because he could use the line (paraphrased) that "I have given my eyesight in service of my country." or the like, and had standing like no one else in the Continental Army.
But having a low opinion of Congress, and being willing to shatter the fledging nation to pursue that, are two different things.
We never had to find out how far they'd go OTL because Washington defused it, but that doesn't mean that no Washington means military authority ultimately trumps civilian.
I think a lot depends on how much the alternate figure is someone who shares Washington's view - Washington may have had a volcanic temper, but he fought to keep it under control. Not all of his fellows did, and it would not be very hard (not necessarily likely, but not hard) for someone with less, in a word, composure to make a very bad decision here.
On not being president for life: What, no credit to John Adams?
On Jefferson:
I don't see why two terms based on Washington's example was inevitable (or necessarily beneficial) - and we know what he tried to do OTL as president.
I guess what this all boils down to me, as someone who is a Washington fan:
Could Washington being lost have devastating consequences? Yes. But the US survived its first generation (1783-1808, give or take) without him in power for most of it. I think that's telling.
