Sen. John Cornyn (R-TX) warned on Thursday that the U.S. needs to continue to monitor the “shifting loyalties” of Saudi Arabia, amid concerns that Riyadh is pivoting away from its traditional allies and toward Islamist actors. 

The Texas senator, who serves on the Senate intelligence Committee and foreign relations committees, told Jewish Insider that while he supports the Trump administration working to add Saudi Arabia to the Abraham Accords, the U.S. should be cognizant of “shifting loyalties and alliances there.”

“The Abraham Accords were a huge and important development, and I think it’s something worth continuing to try to expand and encourage, but I think we have to go in with our eyes open and realize there’s a lot of shifting and maybe even divided loyalties occurring in this region,” Cornyn told JI. 

“Qatar has been problematic for all sorts of reasons that we all know, playing both ends against the middle, and I think Saudi Arabia is probably looking to figure out how to gain advantage, but my hope would be that we continue to put pressure on Iran and its proxies, which we’ve done,” he continued.

Talking to JI a day after Israeli Prime Minister Benjamin Netanyahu’s White House sitdown with President Donald Trump that largely focused on Iran, Cornyn said that he was skeptical of the regime’s ability to conduct diplomacy with the U.S. or honor the terms of any agreement. 

“I think diplomacy is destined to fail because they’re not going to live up to one sentence, one word of any negotiated agreement, so they can be depended on to cheat. They are determined to destroy Israel and start a war in the Middle East. I know the president is taking it very seriously,” the GOP senator said. “I think the president is preserving all of his options, but again, how do you negotiate with somebody who cheats and who will not abide by any part of any negotiated agreement?”

“I don’t think it necessarily hurts at least to suggest that there may be some negotiations that could occur, but again, I don’t expect Iran to stand behind any negotiated outcome. I think given their commitment to the destruction of Israel, and obviously they are an ideological movement, a theocracy,” he added. “Negotiating with somebody like that is asking them to change who they are, and that will never happen.”

Despite this, Cornyn argued that it was important for the U.S. to “acknowledge that any military action against the regime in Iran would likely spill over to other places.”
