WASHINGTON — Three days after the Trump administration evicted the Palestine Liberation Organization from its offices in Washington, Jared Kushner defended the latest in a string of punitive actions against the Palestinians and insisted that none of them had diminished the chances of a peace accord between Israel and the Palestinians.

Speaking on Thursday, 25 years to the day after the Oslo peace accords were signed on the White House lawn not far from his West Wing office, Mr. Kushner said President Trump had actually improved the chances for peace by stripping away the “false realities” that surround Middle East peacemaking.

“There were too many false realities that were created — that people worship — that I think needed to be changed,” he said in an interview. “All we’re doing is dealing with things as we see them and not being scared out of doing the right thing. I think, as a result, you have a much higher chance of actually achieving a real peace.”

Mr. Kushner said he did not want to be too critical of the Oslo accords, which created the framework for peace negotiations over the last three decades. But he cast his own efforts as a radical break with the past, evincing little nostalgia for the historic images of Bill Clinton drawing together Yasir Arafat and Yitzhak Rabin in September 1993.
