You may be right. But, the alternative is even worse. Sometimes, foreign policy is a binary choice. In this case, we can encourage and support the Saud/Israeli alliance, or we can negotiate with Iran which will only guarantee their eventual development of a working nuclear device that is payload capable and the missile tech to deliver that payload.
The only chance this works out well is if Iran collapses in on itself and the more moderate, secular governing elements in Turkey wrest control from Erdogan and his crew. Over the last few years, there have been hints that both could happen under better circumstances.
Saud likely will fail. But, it’s our job to ensure Iran and Turkey fail first.
Fantasy.
Learn the lesson of Afghanistan. The Turks and the Persians are being governed according to their nature. Liberal democracy is anathema to both (and after the damage it's caused our people, should be here as well).
The idea that tinkering with/bribing/bombing sectors of those nations will turn them into something they are not is a silly dream.
