Avigdor Lieberman never misses a chance to speak his mind. And thats exactly what the Foreign Minister did regarding the Palestinian Authority this week. He said every conversation begins with claims by the P-A that Israel is not sincere in negotiations. Lieberman called the tactic a larger scheme that seeks to delegitimize Israel. He said another favorite tactic of the P-A is to get foreign governments to issue arrest warrants for Israeli officials. Lieberman argued the Government cannot cooperate with the Palestinians on security and economic matters while they continue to file lawsuits against Israel.
