President Donald Trump’s son-in-law has hinted that the United Arab Emirates may not be the last Arab nation to establish full diplomatic ties with Israel.

“I do think that we have other countries that are very interested in moving forward to establish diplomatic relations with Israel,” Jared Kushner told CNBC in an interview this week.

“And then, as that progresses, I do think it is an inevitability that Saudi Arabia and Israel will have fully normalized relations and they will be able to do a lot of great things together.”

​Saudi Arabia has remained surprisingly silent on the landmark agreement, despite other regional Arab nations of Bahrain, Egypt, Jordan and Oman welcoming the breakthrough. Kushner, who has developed a close relationship with Saudi Crown Prince Mohammed bin Salman, has downplayed the lack of response from ​Saudi Arabia.

“We just had the first peace agreement in 26 years and now you’re saying: ‘Well, we want to get somebody else on board right away,’” Kushner said.

Last Thursday, the United Arab Emirates and Israel on Thursday announced a US-brokered deal that will see the Emirates become the third Arab nation to fully normalize diplomatic relations with Israel, after Egypt in 1979 and Jordan in 1994.
