The "winners" aren't getting treated much better - war-zones don't magically stabilize afterwards, they remain unstable. In part, because anyone who seizes power by force will have no choice but to maintain it by force; in part, because lawlessness is an environment where old scores (real or imagined) get settled by the gun with no regard for "due process", innocence or guilt, or whether the supposed crime was last week or last millenium; in part because businesses that sell arms do well when instability is maintained and lose custom when peace is restored, giving them a significant motive to ensure instability remains as long as possible; in part because Russia and China have zero interest in seeing UK/US-backed regimes any more than the US/UK is partial to Russia/China-backed takeovers; but also in part because the successive kicking over of hornet's nests in the region for the past 70 years by assorted outside powers (ie: all of them) has led to the formation of ultra-nationalist and ultra-theological extremist movements who don't give a rat's what happens to their own country, just so long as it's them that are doing the happening.
The French Revolution resulted in societal collapse for France. Sure, under the Royalists it wasn't doing great, but the mass slaughter (which didn't stop at Royalists) wiped out most of the intellectuals, free-thinkers, craftsmen and entrepreneurs. The result was anarchy, followed by the rise of a totalitarian State.
The American Revolution was bankrolled by businesses, armed by the French (mostly the Royalist French, with the result that the French Revolution caused untold suffering in America) and hijacked by the slavers. Oh, it was a genuine upswelling, perfectly honest with very legitimate grievances, but by the time it actually turned into a mass movement, the honest, aggrieved parties had largely lost any control. What we recognize as America's independence from Britain was, tragically, also the moment it became a slave state to corporate interests. Americans never got to enjoy their freedom, and what little freedom they actually had has eroded. Not because of any change, but because the rot was actually built into the system from the start.
The Russian Revolution suffered a similar - but far worse - fate. Instead of multiple corporate interests, you had a single cult interest, and instead of a few hundred "undesirables" vanishing every decade or so, they had a few million. But ultimately, that's merely a matter of degree, not a matter of substance. A small lever can lift a paperweight, a large enough lever and a place to stand can shift a planet. Still a lever, same physics, nothing but the scale has changed and scale simply isn't significant.
The Cromwellian Revolution set up a hereditary theocracy in Britain that was so despised and so utterly beyond evil that the son of the executed King was actively petitioned by the nation to return from exile.
Revolutions have never, in all of human history, been kind to those who actually wanted good things to happen to their nation.
If the Brits storm the embassy, they will be in violation of International Law. Diplomatic status isn't a national law issue. You only have to look at the absolute horror the rest of the world felt when Iran stormed the US Embassy to see what will happen. Britain would, rightly, be expelled from the EU and isolated by sanctions from the rest of the world. No, their "special relationship" with the US won't help - in part because the US doesn't see anything special about it, but also because they're a few thousand miles further away. Britain, whether it likes it or not, IS utterly dependent on the patience, tolerance and goodwill of Europe. Push Europe too far and Britain becomes the first EU colony.
Do I think it likely? Cameron is insane, Clegg is Cameron's pet poodle, the Liberal Democrats daren't bring down the coalition by walking out because the utter hatred they've engendered will cost them every last seat in Parliament and they know it. So it really is all down to Cameron. And, as I've said, he's insane. Truly insane. Dangerously so. I wouldn't be the least bit surprised if he ordered the SAS to storm the embassy (as per the Iranian one when it was seized by terrorists). Nor would I be surprised if he gave the order to give no quarter. He truly is delusional enough to regard himself as divinely entitled.
