WASHINGTON -- Republicans and Israeli officials were quick to express outrage after U.S. Senate Majority Leader Chuck Schumer sharply criticized Israeli Prime Minister Benjamin Netanyahu's handling of the war in Gaza and called for Israel to hold new elections. They accused the Democratic leader of breaking the unwritten rule against interfering in a close ally鈥檚 electoral politics.

Senate Republican Leader Mitch McConnell reacted to Schumer by saying it was 鈥渉ypocritical for Americans who hyperventilate about interference in our own democracy to call for the removal of a democratically elected leader.鈥

House Speaker Mike Johnson said Schumer's call for new elections was 鈥渋nappropriate.鈥 Even Benny Gantz, a political rival of Netanyahu and member of Israel's war cabinet, said Schumer's remarks were 鈥渃ounterproductive.鈥

Schumer's stinging rebuke of Netanyahu 鈥 the senator said the Israeli leader had 鈥渓ost his way鈥 and was an obstacle to peace 鈥 was certainly provocative but it was hardly norm-breaking. U.S. leaders, as well as American allies, are more frequently butting into electoral politics beyond the water鈥檚 edge.

Look no further than the close and historically complicated relationship that American presidents and congressional leaders have negotiated with Israel leaders over the last 75 years.

鈥淚t is an urban legend that we don鈥檛 intervene in Israeli politics and they don鈥檛 try to intervene in ours,鈥 said Aaron David Miller, a senior fellow at the Carnegie Endowment for International Peace, who worked as a Middle East negotiator in Republican and Democratic administrations. 鈥淲e do intercede and they do intercede in ours.鈥

In 2019, with just weeks to go before Netanyahu faced a difficult election, then-U.S. president Donald Trump abruptly declared the U.S. was recognizing Israel鈥檚 sovereignty over the disputed Golan Heights, giving Netanyahu a political boost just when he badly needed it.

In 2015, Republican House Speaker John Boehner invited Netanyahu to deliver an address to Congress during sensitive negotiations about Iran鈥檚 nuclear program and shortly before a national election in Israel.

Boehner did not coordinate the invitation with former president Barack Obama's administration. Obama declined to invite Netanyahu to the White House during the visit, with White House officials saying that holding such a visit so close to Israel's election would be inappropriate.

The standard Obama set for a White House visit wasn't one Bill Clinton subscribed to years earlier. In April 1996, Clinton invited Israeli Prime Minister Shimon Peres to the White House to sign a US$100 million counter-terrorism accord shortly before an Israeli election. Years later, Clinton acknowledged in an interview that he was trying to give Peres a boost with voters.

It didn't work; Peres lost to Netanyahu.

In practice, keeping out of allies鈥 elections has been more of a professed American value than enshrined protocol. U.S. leaders have frequently demonstrated a 鈥渧arsity versus junior varsity鈥 approach to how overtly they noodle in the internal politics of friends, says Edward Frantz, a University of Indianapolis historian. The bigger the ally's economy, the less likely American leaders are to meddle openly in its elections.

鈥淎merican politicians want to have it both ways,鈥 Frantz said. 鈥淭here are moments when American leaders want to and need to speak out and have their say. But there is reason to stay close to the lines on elections. You don鈥檛 want foreign governments to interfere in our own internal politics, either.鈥

The lines have only become blurrier in recent years, and are being tested by how world leaders are approaching November's Biden-Trump rematch.

This past week, during a White House visit on the 25th anniversary of Poland's accession into NATO, Polish Prime Minister Donald Tusk didn't obscure his desire to see Biden win another term.

鈥淚 want you to know that your campaign four years ago was really inspirational for me and for so many Poles,鈥 said Tusk, with conservative Polish President Andrzej Duda by his side. "And we were encouraged ... after your victory. Thank you for your determination. It was something really important for 鈥 not only for the United States."

Tusk later singled out Johnson, the Republican House speaker, to blame for Washington's deadlock on a spending bill with US$60 billion in aid for Ukraine, which is running low on ammunition and arms in its war with Russia.

鈥淭his is not some political skirmish that has significance only here, on the American political stage,鈥 said Tusk. He told reporters that inaction by Johnson could 鈥渃ost thousands of human lives in Ukraine.鈥

Last week, Biden slammed Trump for hosting Hungarian Prime Minister Viktor Orbán, who has described a possible comeback by Trump as the 鈥渙nly serious chance鈥 for an end to the war in Ukraine.

Hungary, like the U.S., is a member of NATO. Orbán has become an icon to some conservative populists for championing 鈥渋lliberal democracy,鈥 replete with restrictions on immigration and 2SLGBTQ+ rights.

Biden during a recent campaign event noted that Trump was meeting Orbán, and said the Hungarian leader is "looking for dictatorship.鈥 Hungary summoned the U.S. ambassador to Budapest, David Pressman, to register displeasure with the president's comments.

White House national security adviser Jake Sullivan said the president stood by his comments.

鈥淥ur position is that Hungary has engaged in an assault on democratic institutions, and that remains a source of grave concern to us,鈥 Sullivan said.

The Schumer comments in the midst of Israel's difficult five-month war offer new strain to the U.S.-Israel relationship.

That relationship already has seen tensions between Biden and Netanyahu mount as the Palestinian death toll rises and innocent civilians suffer while the U.S. and others struggle to get aid past Israel's blockade and into Gaza. National elections are set for 2026 in Israel though they could well come earlier.

Biden, in a brief exchange with reporters on Friday, said he thought Schumer had delivered 鈥渁 good speech." The president and White House officials, however, stopped short of endorsing Schumer's call for elections.

There have been other moments of deep tension in the U.S-Israeli relationship.

Former U.S. president Dwight Eisenhower pressured Israel with the threat of sanctions into withdrawing from the Sinai in 1957 in the midst of the Suez Crisis. Ronald Reagan delayed the delivery of F16 fighter jets to Israel at a time of escalating violence in the Middle East. Then-U.S. president George H.W. Bush held up US$10 billion in loan guarantees to force the cessation of Israeli settlement activity in the occupied territories.

But the press by Schumer for new elections ventures into uncharted territory.

鈥淎ll of those other crises were sort of one-offs,鈥 Miller said. 鈥淭hey were efforts to move Israel in a focused, discrete way on a specific issue. What you have now after years of Netanyahu鈥檚 premierships is a fundamental crisis of confidence, which cuts to the core of the U.S.-Israel relationship.鈥
