This isn't the first time the U.S. and Israel have disagreed over Gaza

U.S.-Israel relations are now strained over Gaza — and it's not the first time Israel's military operations there have drawn criticism from the White House.

The year was 1956. Israel, Britain and France had just invaded Egyptian territory in a bid to take over the Suez Canal, which Egypt had decided to nationalize.

U.S. President Dwight Eisenhower stepped in, ending the brief conflict. But in the months afterward, Israel resisted a United Nations resolution that called for it to pull its troops out of the Gaza Strip, then controlled by Egypt.

"Repeated, but so far unsuccessful, efforts have been made to bring about a voluntary withdrawal by Israel," Eisenhower said in a nationally televised speech. "It was a matter of keen disappointment to us that the government of Israel, despite the United Nations action, still felt unwilling to withdraw.

Israel got the message, and withdrew from Gaza shortly afterward.

So here we are again, 68 years later, with a few a new twists.

President Biden supports Israel in its war with Hamas. But he's warning Israelis against a military offensive in the southern Gaza city of Rafah at a time when more than a million Palestinian civilians are taking refuge there.

Top U.S. and Israeli officials held a virtual meeting Monday but did not reach a breakthrough.

"They agreed that they share the objective to see Hamas defeated in Rafah. The U.S. side expressed its concerns with various courses of action in Rafah. The Israeli side agreed to take these concerns into account and to have follow up discussions," the U.S. and Israel said in a joint statement.

So just how strained are relations right now?

"I do see a very, very real risk for the state of Israel and its long-term interests," said Jeremy
