Current EU president Poland said Wednesday that Israeli security must not be threatened should any change occur in the Middle East due to the Palestinian bid for statehood. Prime Minister Donald Tusk said that Poland's position depends on the wording of any UN resolution. He noted Poland's decades-long good relations with Arab nations,and especially with the Palestinians,but said Poland will be 'tough' in making sure that no changes in the region threaten Israel's security. Palestinian President Mahmoud Abbas is to address the U.N. General Assembly later this week and request full U.N. membership. With peace talks deadlocked for the past three years,the Palestinians believe a strong international endorsement will improve their position in future negotiations. Poland's former president and Nobel Peace laureate Lech Walesa said Wednesday it was a 'difficult task' to reconcile the rights of the Palestinians and the Israelis. I support the rights of Israel,but I also support the rights of the Palestinians. Walesa said,I will continue to offer my support but it is a difficult task. President Barack Obama will publicly push for the Palestinians to drop their bid and return to direct peace talks. Warsaw has been urging the 27-nation European Union to work out a joint stance on the Palestinian bid.
