Republican leaders Saturday criticized the Trump administration’s possible move to sign a memorandum of understanding with Iran to end the war and reopen the Strait of Hormuz. While President Donald Trump did not mention Iran’s nuclear program, Tehran reportedly said that the current talks did not address nuclear issues.

In a strongly worded post on X, Senator Lindsey Graham (R-S.C.) said the consequences of such a deal could pose a “nightmare for Israel.”

“If a deal is struck to end the Iranian conflict because it is believed that the Strait of Hormuz cannot be protected from Iranian terrorism and Iran still possesses the capability to destroy major Gulf oil infrastructure, then Iran will be perceived as being a dominate [sic] force requiring a diplomatic solution,” he wrote.

“This combination of Iran being perceived as having the ability to terrorize the Strait in perpetuity and the ability [to] inflict massive damage to Gulf oil infrastructure is a major shift of the balance of power in the region and over time will be a nightmare for Israel.”

Pushing back on the idea that Iran should be allowed to hold such leverage over the region, he added, “It is important we get this right.”

The Senate Republicans’ X account and Sen. Tom Cotton (R-Ark.) reposted Graham’s statement.

Other leading Republicans joined their voices to the growing chorus of criticism.

“The rumored 60-day ceasefire — with the belief that Iran will ever engage in good faith — would be a disaster,” posted Sen. Roger Wicker (R-Miss.).

“Everything accomplished by Operation Epic Fury would be for naught!” he warned.

Already on Friday, Wicker was posting his reservations on X, accusing Trump’s advisers of leading him to poor decisions on the conflict.

“We are at a moment that will define President Trump’s legacy,” he wrote. “His instincts have been to finish the job he started in Iran, but he is being ill advised to pursue a deal that would not be worth the paper it is written on.”

“Our commander-in-chief needs to allow America’s skilled armed forces to finish the destruction of Iran’s conventional military capabilities and reopen the strait,” he continued. “Further pursuit of an agreement with Iran’s Islamist regime risks a perception of weakness.”

“We must finish what we started. It is past time for action,” he concluded.

Ted Cruz said he was concerned about the reports on the deal and “prayed” they were wrong.

“I am deeply concerned about what we are hearing about an Iran ‘deal,’ being pushed by some voices in the administration,” he wrote on X. “President Trump’s decision to strike Iran was the most consequential decision of his second term. He was right to do so, and we achieved extraordinary military results — including destroying all of their missiles & drones and sinking their entire navy.”

“If the result of all that is to be an Iranian regime — still run by Islamists who chant ‘death to America’ — now receiving billions of dollars, being able to enrich uranium & develop nuclear weapons, and having effective control over the Strait of Hormuz, then that outcome would be a disastrous mistake,” he added. “The details are still coming out — and I pray the early reports are wrong — but the fact that Biden’s Rob Malley is praising the deal is not encouraging.”

Cruz also said that Trump, who “believes in peace through strength,” should continue to “enforce the red lines he has repeatedly drawn.”
