The sad thing is that nothing there will get better, it's not like they will turn into a democracy..
There is an old smart sentence from the African politics and regime changes.
"A full lion is better than an hungry one.."
Mubarak is full, the "new lion" will be hungry, and will need to feed HIS people with power position jobs, corruption will be back sooner then they expect..
It is possible that the outcome will be a negative outcome to the West, however it could go the other way as well.
The US viewed Vietnam in a very negative way after fall of Saigon 1975 that they placed an embargo on till it was lifted in 1993. And since then the relationship between Washington and Hanoi is much closer than it ever was (much closer than the Franco US time, Ngo Dinh Diem, or Ngyen Van Thieu time).
The US is extremely negative to Cuba for many years and currently, however Cuba hasn't become a rogue state that threaten its neighbors or its population.
Both Cuba & Vietnam as well as every other countries in the world are corrupt, but they didn't become rogue nations as painted by the spin doctors. And, the US is far from being one that is with out corruptions.
IMHO, we should give the Egyptian a chance to determine their future instead of injecting negativities and what if.
