Yitzhak Segev, once the Israeli military governor of Gaza, funded Ahmed Yassin and encouraged antagonism in him against secular Palestinian political forces.
It's funny for Israel to fund the founding of Hamas, encourage Muslim religious antagonism against more internationally appealing secular Palestinian figures, and then turn around and whinge about the people that they bankrolled. Hamas was bankrolled by Israel and its no secret.
Working people around the world know this and stand in support of Ahmad Sa'adat and other Palestinians to live free of the barbarism and tyranny Zionism is inflicting on them right now.
