According to the Jerusalem Post, Egypt’s new border wall with Gaza is sparking a crisis for Hamas. Reporter Khaled Abu Toameh concludes:
An all-out confrontation between Hamas and Egypt will undoubtedly undermine Mubarak, because it will make him appear as if he's helping Israel and the US in their war against the movement. A confrontation will also send the message that Mubarak is also involved in the "siege" on the Gaza Strip.
Hamas, on the other hand, stands to win from a standoff with a regime that is regarded by many Arabs and Muslims as a puppet in the hands of the Israelis and Americans. And any victory for Hamas is also a victory for Damascus and Teheran.
A look at LA Times coverage of the Egyptian security barrier shows that very spin game in action.
