If the OT Stormies are really the Clones from the Prequels, it makes ROTJ (awful film IMO) even more pathetic.
They would have killed those Ewoks without even trying.
But I hate ROTJ anyway, by far the most predictable, boring and goody-kissy-everythingisfinenowy film. But that's not the point here.
Maybe the most satisfying answer would be, that there are both: recruited troops to stabilise the Empire: If the executive forces comes from within the community, a rebellion is less likely.
And there are still the Clones, too.
PVS, sit down, have a drink. You're right of course, but they're still in denial. "It can't be this easy, it's SW!"....
People, GL is making this saga up as he goes. I am quite sure he never thought of the stormtroopers to be clones when he made ANH. And now... they are.
Much the same this I don't believe GL thought of Anakin to be a child when he started his Jedi training, but more persuaded by OB1 to learn about the force. ("follow old OB1 on some damn fool idealistic crusade).
