Israel gave a muted response on Sunday to a major arms deal between the United States and Saudi Arabia announced a day earlier during the visit to the region by US President Donald Trump.
"This is a matter that really should trouble us," said Energy Minister Yuval Steinitz prior to the weekly cabinet meeting, although Prime Minister Benjamin Netanyahu made no mention of the deal in his customary public remarks.
Netanyahu has voiced his wish to improve ties with Saudi Arabia and other Gulf states as part of an initiative that would draw the Palestinians into an eventual peace deal and as a broad front against Iran's nuclear ambitions.
Israel has always been wary of maintaining its military edge and Steinitz said he hoped to hear details of the deal. Trump and his entourage touch down in Israel on Monday.
