Over the last month, Israeli leaders have made a string of friendly visits, gestures and statements towards Arab leaders in the Gulf, positioning Israelinfo-icon for what appears to be a more overt alliance with Gulf states, from Oman to Bahraininfo-icon, Saudi Arabiainfo-icon and the UAEinfo-icon.

The Palestinian struggle for statehood, meanwhile, has been "cast to the margins" by the leaders of these same Gulf countries, said Saeed Khan, a senior lecturer in Near East studies at Wayne State University in Detroit.

"It seems as though, among the Saudis, UAE and to a certain degree Oman, they are clearly putting their stock with the official Israeli political line. They're either turning a blind eye or seemingly not at all interested in the Palestinian issue," Khan told Middle Eastinfo-icon Eye on Thursday.

Khan's comments come as Israel's intelligence and transport minister called for a deeper partnership between his country and its neighbours on the Arabian Peninsula, including in the fields of transportation and tourism.

"In my view cooperation between Israel and the Gulf states can and should be expanded," Yisrael Katz told Reuters via email on Thursday, a few days after he returned from a visit to Oman earlier this week. "Israel also has a lot to offer when it comes to water desalination and irrigation, agriculture and medicine."

Katz wasn't the only Israeli leader to visit the Omani capital, Muscat, in recent weeks.

Late last month, Israeli Prime Minister Benjamin Netanyahu made a surprise visit to the Gulf country, meeting with its leader, Sultan Qaboos bin Said. Israel's Sportsinfo-icon and Culture Minister Miri Regev was also in the nearby UAE last month, where she met Emirati officials and toured the worldinfo-icon's third-largest mosque, in Abu Dhabiinfo-icon.

Khan said leaders in Israel and the Gulf are experiencing a "sense of empowerment" thanks to USinfo-icon President Donald Trumpinfo-icon.

He explained that Washington has given a green light to its allies in both places to work jointly and openly on their common goal: building a united front opposed to Iraninfo-icon.

At the midway mark of the US president's first term in office, and with Trump facing investigations at home related to possible collusion between his election campaign team and Russiainfo-icon, there is a "moment of desperation" to strengthen ties between Israel and Gulf countries, Khan said.

"There's an expedited timeframe by which the Gulf states and Israel are operating in order to provide a united front and exert maximum pressure against Iran," he told MEE.

The Palestinian issue

The White House has also been readying a peace plan to end the Israeli-Palestinian conflictinfo-icon, dubbed by the Trump administration as the "deal of the century".

But Palestinian leaders have already signalled that they will not accept Washington's proposal.

"The plan calls for having a Palestinian state with provisional borders on half of West Bank and the Gazainfo-icon Strip, without Jerusaleminfo-icon, and calls for humanitarian solutions to the refugee issue," a Palestinian official told MEE in May.

Still, Saudi Arabia's powerful Crown Prince Mohammed bin Salman is pushing to convince Palestinians to take the offer.

Speaking in New York in April, bin Salman said Palestinians should come to the negotiating table or "shut up and stop complaining".

Nonetheless, Arab citizens, including in the Gulf region, seem uninterested in an alliance with Israel without a just resolution for the Palestinians.

A 2017 poll by the Arab American Institute, based in the US, showed that only two percent of Saudis and one percent of Emiratis favour an anti-Iran alliance with Israel if Palestinian rights are not addressed.

Khan said Gulf states may be moving toward censoring pro-Palestinian voices inside their own countries as part of a larger crackdown on dissent.

He said leaders in the Gulf may also try to convince their citizens that Iran, not Israel, is the real threat to them.

"If in the calculus that means that the Palestinian issue either has to be marginalised, forgotten or even reassessed, it's highly likely that the public will go along with the state," Khan said.
