WASHINGTON — President Trump will release a long-awaited Middle East peace plan on Tuesday that is expected to include a proposal for new Israeli borders and provide for Israeli sovereignty over much of the Jordan Valley, a strategic area on the eastern frontier of the West Bank abutting Jordan.

Mr. Trump will be joined at the White House for the announcement by Benjamin Netanyahu, Israel’s prime minister.

Palestinian leaders, who no longer speak to Trump officials, are likely to oppose each of those elements, even if they are combined with the economic rewards of $50 billion or more that the Trump administration says it can deliver.

That is why many analysts say the plan, developed under the supervision of Jared Kushner, the president’s son-in-law, is relevant mainly for its potential effect on Israel’s March 2 election, which is likely to decide the fate of the embattled Mr. Netanyahu, and as a distraction from the Senate’s impeachment trial of Mr. Trump.
