I'm not speaking of Mubarak, his problem was corruption in the Egyptian economy. But, regarding military prowess and affairs he was good for Egypt but also for Gaza he didn't order any action against the tunnels. In that sense, yeah he was good. The current leader in my opinion is worse especially the way he's dealing with the protestors, freedom of speech, he's going way overboard trying to put random people jail and scaring people through violence. This will not work in my opinion, he's also killed many civilians in the Sinai who go unreported. He's acted against tunnels in Gaza based on false information, at least open the border. During mubarak era, he closed border for the most part and Palestinians had to resort to tunnels. This guy is closing both and Israel also gets a free pass to close all seven borders even though the Dutch offered security system to monitor goods. They don't allow any normal basic goods to enter Gaza except on a fixed basis where there will always be shortages to food, medicine, fuel, etc....
I've yet to see what he's going to do with the Egyptian economy and what happens if he's elected as president. If he changes his ways and enables freedom to Egyptian parties and people's and tackles corruption in Egypt and supports palestine then my opinion will change on him. But, being the person I am if cant justify his current path.
