For months, the Biden Administration bitterly opposed an Israeli invasion of Hamas’s last stronghold in Gaza. The mantra was that Israel had “no credible plan” to evacuate the city’s 1.3 million civilians. Yet the Israelis went ahead anyway, and two weeks later they have safely evacuated an estimated 950,000 people. This was supposed to be impossible. Rafah became a red line for Mr. Biden on the logic that there was no way to conduct a major operation with all those civilians present. That was the justification for the President’s arms embargo. “We’re walking away from Israel’s ability to wage war in those areas,” he said. Even as the evacuation got under way, Secretary of State Antony Blinken repeated that Israel had “no credible plan.” National security adviser Jake Sullivan added, “We still believe it would be a mistake to launch a major military operation into the heart of Rafah.” When the evacuation began to work, the Biden team moved on to criticizing Israeli readiness for the “day after” the main fighting, as if success in Rafah were a foregone conclusion. Finally on Tuesday, the Administration claimed credit. “It’s fair to say that the Israelis have updated their plans. They’ve incorporated many of the concerns that we have expressed,” a senior U.S. official told reporters. He also said the Rafah operation might create “opportunities for getting the hostage deal back on track”
