An umbrella organization of nationalist grassroots organizations is beginning a public campaign against Prime Minister Sharon\'s intentions to agree to a Palestinian state west of the Jordan River. Headed by Nadia Matar and Moshe Leshem, the group demands that Sharon retract his support for a Palestinian state - and if not, it will work to topple his government. The National Union-Yisrael Beiteinu party is so far not cooperating, however. Although, contrary to reports yesterday, an official decision has not yet been made, it does appear that the party will remain in the government. MK Yuri Stern told Arutz-7 that at present, they are more concerned with the war against terrorism, and that they will deal with \"diplomatic developments\" as they occur. The two factions of the National Union party, Tekumah and Moledet, will decide early next week if they wish to resign from the government. At present, Tekumah is leaning towards remaining, while Moledet - the late Rehavam Ze\'evi\'s party - is not as sure.
