The Palestinians have a right to confront Israel, and a third intifada may be on the way, senior Palestinian official Nabil Shaath said on Friday.

Shaath, an adviser to Palestinian Authority leader Mahmoud Abbas, said in a July 3 interview by France 24 that Saudi Arabia’s King Abdullah had pledged $1 billion in support of the second intifada, which lasted from 2000-2005, and that today, the Arabs and the whole world would stand by the Palestinians if things continue as they have been. Europe will not tolerate an Israeli annexation of the West Bank, he said.

Shaath, who claims to have been U.S. President Donald Trump’s professor at the Wharton School of the University of Pennsylvania, said that Trump had been a poor student and is unpredictable, specifically with regard to the issue of Israeli annexation of parts of the West Bank. In addition, Shaath said that PLO chairman Yasser Arafat had been “martyred” by Israeli poison because of his position and that the United States will cease to be the leader of the world within five years.
