US President Donald Trump heads for Israel and the Palestinian territories Monday as part of his first trip abroad since taking office, hoping to renew peace efforts but with controversy trailing him.

The unpredictable president arrives having already upturned expectations when it comes to the decades-old Middle East conflict, giving Palestinians more hope than they may have anticipated and disappointing right-wing Israelis who heralded his election.

He has spoken of reaching “the toughest deal to make”, one that has long bedevilled US presidents, vowing “we will get it done”.

But he is also contending with a raft of problems back home, including a special counsel investigating whether his associates colluded with Russia.

Any leader would face an enormous challenge in seeking to bring the Israelis and Palestinians together for meaningful talks, and Trump´s inexperience and domestic political struggles will only add to it.

Beyond that, Trump has faced criticism from Israelis in recent days related to the White House´s approach to the ultra-sensitive status of Jerusalem.

Concerns have also been raised over Trump´s sharing of intelligence with Russia said to have originally come from Israel.

“I think the trip´s in a lot of jeopardy being able to be productive because of all the chaos and controversy that´s going on in Washington,” Dan Shapiro, US ambassador to Israel under Barack Obama and now a senior fellow at Tel Aviv´s Institute for National Security Studies think tank, told AFP.
