In an interview with Al Manar, Mahmoud Al Zahar, the strong man of Hamas in Gaza criticized harshly the agreement with Fatah... So seems to me it will not be implemented...
On the other hand, new information surfaced about the position of Hamas from the Syrian issue. It seems that the military leadership wants to keep the strong relations with Syria, while the political leadership is hesitating. The military leadership knows that there is no alternative to Syria.. they also know how much aid they got from Syria in the war of 2008...
