tyrant leaders eh? I can't wait to see the new era of freedom and compassion that these usurpers would bring with them. You will be free to do do what your told, when you are told, and how you were told. If you are a female, you won't even enjoy that much freedom. Christians? Jews? You'll be free to kill them wherever they may be. Oh, and wait until your new islamic benefactors end trade between your states and the rest of the world. Then you will be free to be even more poor than you now are. Won't that be fun? But don't worry, in the end, you'll be free to die by the bombs that we drop on your cities after your new leaders realize that war is the only option for you.
If the islamists take over they will, of course, be tyrants but that doesn't change the fact that Mubarak and company are tyrants as well. Revolution is a dangerous game but the people are clearly past the point where the "evils are sufferable". A year from now they may find that they made a terrible choice but I find it hard to be critical of people who want out from under a dictator.
