"I have no doubt that if they (Qatar) want it and are willing to pay, sooner or later they will get it," Energy Minister Yuval Steinitz, who sits in Prime Minister Benjamin Netanyahu's security cabinet, told Ynet TV.
"This is a supposition that we must take into account," he said, arguing that the US administration "ultimately looks out for American interests," especially in the face of rival stealth jets on offer from Russia and China.
Reuters reported on Oct. 7 that gas-rich Qatar had submitted a formal request to buy the F-35, a Lockheed Martin plane that has so far been supplied only to Israel in the region. Israel, with which Washington consults on such sales, said it would be opposed.
Emphasizing that this position would not change, a spokesman for Steinitz said in a follow-up statement to Reuters that should such a sale go ahead, Israel would demand "appropriate compensation" - an apparent reference to US defense assistance.
US officials have been open to selling the F-35 to the United Arab Emirates after it and Bahrain normalized relations with Israel on Sept. 15. But they have been tight-lipped on Qatar's bid to buy the jet.
Successive US administrations have sought to preserve Israeli military superiority in the region. Steinitz noted, however, that there had been past US sales of advanced aircraft to Arab countries over Israeli objections.
Israel initially voiced misgivings about the UAE getting F-35s. The Netanyahu government dropped these on Friday after Defense Minister Benny Gantz returned from Washington with new US security guarantees for Israel.There has been speculation in Israeli media that the Trump administration could hold out the F-35 as an inducement for Qatar to normalize ties with Israel. Qatar has ruled out such a diplomatic move without a resolution to the Israeli-Palestinian conflict.
