I think any objective close observer of the Egyptian scene, can see that Morsi and his group are having a furious fight against anti-revolutionary forces which aim to destabilize the country so that they can blame MB for this. They are using the judiciary, media and thugs to spread chaos through out the country, counter any move, any decision, any change made by Morsi just to see him failing.
This doesn't mean that MB are without mistakes but fact that any revolution must face frantic opposition, should be taken into consideration, and if we were moving smoothly, then we must know that something went wrong.
The MB have been in rule for how long? 9 months? 10 months? I don't think that any sane person should judge them based on this short period given the current circumstances and that we are recovering from a regime change.
As an observer the problem doesn't stem from their rule but how they got to rule,if they had gone through the process of consultation over the constitution and gained power,Egypt,IMO,would not be in the situation it is in now because nobody or organisation could have a legitimate complaint and Egypt would have the full backing of the international community.
The result of the MB winning caused the economy to take a nose dive because to outside observers,especially investors,could not see any return because there is no stability,really The Muslim Brotherhood scored an own goal concerning the constitution that THEY wrote,the fact that their opponents are made up of Muslims,Christians and secularists speaks volumes.
There are two other events that are of note,Hamas opened an office in Cairo and the MB visited Ahmadinejad,of course Hamas are already in the pocket of Iran or Iran are in the Rockets of Hamas,the two events took more priority over actually listening to the Egyptian people,its like the funeral of Margeret Thatcher here,the government did not listen or even ask the British people whether we should spend X amount of millions on such a divisive and hated figure,they only said "its the right thing to do" like it or not and,as an observer,thats exactly what the MB did on the constitution,JMO.
