Yisrael Beytenu chairman Avigdor Liberman slammed Prime Minister Binyamin Netanyahu on Thursday morning ahead of his address before the United Nations General Assembly in New York. 

"Our prime minister is certainly a gifted orator. He knows how to generate headlines and statements," the former foreign minister told Army Radio. The problem, however, according to Liberman, "is deeds."

"Netanyahu is incapable of making decision," Liberman charged. "He doesn't know how to make decision and he doesn't know how to lead any sort of [diplomatic] process."

The Prime Minister was expected to focus his address on the West's nuclear deal with Iran, but Palestinian Authority chairman Mahmoud Abbas' speech on Wednesday night will likely alter these plans. 

In the speech, Abbas declared that the PA is no longer committed to the 1994 Oslo Accords, while condemning Israeli "settlements" in Judea and Samaria, as well as the blockade of Gaza.

Sources close to Prime Minister Binyamin Netanyahu then said he will use his own speech at the UN headquarters on Thursday to decisively attack Abbas's speech directly, exposing what the sources call the lies and incitement in Abbas's address.

Netanyahu's associates, and the Prime Minister himself, have all asserted recently that the Iran deal is the most important issue to bring before the UN Security. The original draft of his speech did, however, include a minor reference to the Palestinian problem. 

But given continued unilateral Palestinian steps in the international arena, including the raising of the PA flag at the United Nations, as well as continued incitement over and terror on the Temple Mount in Jerusalem, Netanyahu chose to shift course and focus his speech as a strong rebuttal to Abbas.
