Yasser Arafat seems to have learned from the zig-zag approach of his former counterpart, Ehud Barak. In the wake of the IDF operation in Khan Yunis overnight, the PLO early today announced that it would not participate in any meetings dealing with security cooperation between itself and Israel. Arafat advisor Nabil Abu Radeina went so far as to condemn what he called the \"Israeli attack\" saying that such operations are part of \"an Israeli plan to weaken the Palestinian Authority and its institutions and to harm the Palestinian people.\" After pressure was exerted by US Secretary of State Colin Powell, the American CIA, and European Union officials, however, Yasser Arafat late this afternoon gave the green light for his representatives to attend the meeting. The US ambassador to Israel is expected to host the gathering in his Herzeliya home this evening.
