Could be all and then some or any mix thereof...
Being a betting man, I'd put my money down on a series of cascading mini-implosions that lead to one big POOF!
Some martial law and anarchy thrown in here and there until the Big One.
Then, yeah, chaos, civil war, wars of acquisition, famine, plague, pestilence, rape, murder and mayhem...all the nasty parts of the bible...
After that?
