Judge yourself
If I judge al-Zahar, supporter of Hamas, I find out that he has lost his mind. He went crazy after hearing the judgment by Egyptian judiciary to name al-Qassam Brigades a terrorist organization. It’s indeed a terrorist faction as it plans to spread chaos in Egypt and kill the Egyptians. Such ruling came to reveal a fact that you acknowledged months before when you decided to stop all hostilities against Israel. You forgot that there is no difference between hostilities and terrorist acts. Egyptian judiciary only repeated a fact stated by your president Mohamed Morsy.
I do wonder when al-Zahar says that only loser armies provoke hostility with Hamas. In fact, there are no loser armies more than Hamas and Hizbolah. Perhaps he meant the Turkish army, which crushed under the Egyptian army feet since Muhammad Ali Pasha, the great, and was defeated by several European armies as well. Perhaps he meant the Qatari army, which I do not know if it exists or the Qatari royal family depends entirely on American bases.
