So now Hamas has to really work for the solution, but this Haaretz (Israeli) report says Tantawi (actual security top of Egypt, not Morsi) - is not trusting Hamas. 

The Hamas leadership is trying to convince Morsi that it is capable of cooperation, at least on the intelligence level, and Hamas leaders – namely Ismail Haniyeh and Khaled Meshal – went as far as offering concrete assistance to Morsi and the Muslim Brotherhood leadership. However, Tantawi has so far showed little enthusiasm for the proposals of Hamas – a movement that up until a few months ago was still financially supported by Iran.
