From what I've read Mugabe siezed land from his countries white farmers and handed it over to military leaders awhile back to gain their support. I hope this ends bloodlessly but the military brass has a lot to lose if they permit the MDC to take power. Under the best case scenario Mugabe will agree to leave in exchange for immunity and sanctuary in some 'neutral' country. I'm not aware of instances in roman history where the emperor ruled long without the support of his military.
However, even if he does agree to cede power and leave, restoring Zimbabwe's' economy could take years or even a decades. Mobs are impatient, uneducated starving impatient mobs prodded by a corrupt military leadership that has much to gain by re-establishing the status quo once Mugabe leaves, may not be willing to wait while the economy is restored.
Hopefully, the amount of time they're taking means they're not doing anything rash. Maybe they'll sit down and figure that they can't keep a 84 year old in power for that much longer just due to age. It's never to early to hope though, but speculation is running rampant so it's impossible to form a good conclusion rightnow. For example over at the
Zimbabwe situation, a news aggregation site, the headlines are reading
As Zimbabwe waits tension rises higher
Deal averts Zim civil war
Zimbabwe blogs: 'Mugabe must go. He must go now'
Zimbabwe Opposition Says It’s Ready to Win Possible Election Run-Off
Mugabe will declare a rigged victory
A wonder that Robert Mugabe could stay on
So the reports are still highly contradictory. However, the bottom line is:
Post-Election Uncertainties Exacerbate Food Shortages In Zimbabwe
This kinda cuts the crap, even if he leaves that's just the first step. Food prices are soaring, and well, what can even be said for their economy? It's going to take a Nobel worthy effort to fight hunger in Zimbabwe.
