Secretary of State Marco Rubio traveled to Israel on Thursday, becoming the latest senior official dispatched to the country by President Donald Trump as the fragile ceasefire between Israel and Hamas extends into its second week. 

Rubio joins several other administration officials and representatives who have made the journey to Israel this past week, on the heels of the signing of the first phase of Trump’s peace proposal, including Vice President JD Vance, White House Special Envoy Steve Witkoff and advisor Jared Kushner.

The swift mobilization of U.S. officials comes as the Trump administration aims to lay the groundwork for the second phase of the deal and works to keep Israeli Prime Minister Benjamin Netanyahu from reigniting fighting in the Gaza Strip and fracturing a delicate peace deal, amid Hamas’ repeated violations of the agreement. 

Vance, in his meeting with Netanyahu on Wednesday, emphasized that Israel is not a “vassal state” that needs to be told what to do. 

The string of high-level visits is “not about monitoring in the sense of, you know, monitoring a toddler,” Vance told reporters alongside Netanyahu. “It’s about monitoring in the sense that there’s a lot of work.”

Meanwhile, ahead of his own visit to Israel, Rubio warned Israeli leaders that the West Bank annexation vote that passed the Knesset this week — championed by far-right MK Avi Moaz — threatened to derail the Trump-orchestrated ceasefire deal.

Chuck Freilich, an associate professor of political science at Columbia University, told Jewish Insider he sees it as a form of U.S. oversight, or “Bibi-sitting,” something he says is “long-standing tradition” in the U.S.-Israel relationship.

“From the U.S. perspective, you want to go over and reassure Israel its legitimate security concerns are not in jeopardy by continuing to adhere to the ceasefire,” said Jonathan Ruhe, a fellow for American strategy at the Jewish Institute for National Security of America. “I imagine that Rubio will be there to more echo and amplify the messages that have already been laid out, assuming the facts on the ground don’t change between now and then.”

While disagreements between the U.S. and Israel are not unusual, the Biden administration’s efforts to oppose Netanyahu’s preferred policies often led to accusations of insufficient U.S. support for the Jewish state.  

During the Biden administration, senior officials, including Secretary of State Tony Blinken, were dispatched to the region to keep Israel from conducting military operations in the southern Gaza city of Rafah. At the time, Biden faced criticism from some in the pro-Israel world for restraining Netanyahu’s government from doing what they saw to be in Israel’s best interest during the war. 

Given Trump’s high popularity in Israel in the immediate aftermath of the hostage-release deal, that blowback is not happening this time around. Freilich says the Trump administration’s exertion of restraint on Netanyahu from going after Hamas to uphold the ceasefire is different. 

“Unlike with Biden, I don’t think there is a war to be won now that the U.S. is blocking,” said Freilich. “Israel has already done most of what it can do. The real problem is with phase two, how to dismantle and disarm Hamas and remove it as the governing body in Gaza. The administration is working on it intensively, including in all of these visits.”

The continued engagement is also a way for the Trump administration to provide Netanyahu cover from the right-wing coalition of his government, which had been more reluctant to end the fighting and make a hostage deal before the complete elimination of Hamas. The Trump administration may see holding them at bay as another way to keep the ceasefire intact.

David May, a senior research analyst at the Foundation for Defense of Democracies, said Rubio will be a worthy asset alongside Witkoff and Kushner, stating that his presence could help Israel get Hamas to “uphold a ceasefire that would effectively dismantle the terrorist group.” 

“Dispatching Secretary of State Marco Rubio is a very positive development,” May told JI. “Rubio possesses immense knowledge of the issues and the actors with his decades of experience operating in U.S. foreign policy.”

This will be Rubio’s fourth visit to Israel since taking office in January. The secretary of state has a plethora of diplomatic experience with the Jewish state and has long expressed steadfast support for Israel’s war against Hamas in Gaza, dating back to his time in the U.S. Senate.
