Demiurge
"History is replete with countervailing examples, and a priesthood that was one or two generations old is extremely unlikely to be able to cope with force of arms specifically wielded against it."
What arms?
In Foundation: The Mayors, the priests controlled the weapons. They turned these weapons off at will. The political leadership's oppression had no teeth.
That's the difference between them and the scientists under the soviet union.
"The concept that a insterstellar empire would no longer have the technical concepts necessary to maintain itself is a bit hard to believe now - information is readily at everyone's finger tips."
In the foundation universe, information is not at everyone's fingertips and the fall of the central power started a general decline. And all characters in the foundation universe operate under these laws and conditions - Asimov's laws.
Incidentally, this has nothing to do with our discussion - unless your argument degraded to - 'the foundation universe is highly improbable and that's why Wienis acted stupidly

'.
"Even now wars are constantly raging, we just choose to ensure that they no longer get to the point where nuclear powers come into direct competition - millions still die."
And what is gained from these wars - these deaths, Demiurge? Do you actually consider the decisions of starting these wars inspired or competent?
"Ask the indigenous american peoples about what happens when one side is clearly not the equal in said ability."
Demiurge, READ my posts before answering them. I already answered this:
History showed that violence worked in some cases; however, in many other cases, violence failed to achieve the desired results.
Violence seems to work only when you're overwhelmingly powerful
(this is a VERY restictive condition, especially in today world) and can afford to assimilate the conquered people after centuries of occupation (I doubt this is still feasible today, though) or just exterminate your enemies (the Roman Empire, for example). It also works when you apply it with scarcity and accompany it by positive stimuli (help for the defeated nation, etc).
"Indeed. Thank you for acknowledging that asimov's aphorism was simply wrong."
I did nothing of the sort.
I pointed out that violence only worked when a very restrictive set of conditions was achieved. Which is a large disadvantage of this 'shoot first, ask questions later' mindset.
"Is there any question that without violence of some sort either committed or the threat of overwhelming capability of it Sadaam Hussein would still be the dictator of Iraq and in a position to pass on his position to his children?"
Is there any question that USA helped this very dictator in the past strengthen his hold on power, in exchange for very short-term gains?
Or that MILLIONS died - and are dying - in Irak, during this war?
Or that the irakian population resents USA for invading them, in order to steel their oil (a correct assumption on their part)?
How much did this war cost USA? For what gain?
