Former Israeli and Palestinian peace negotiators have drawn up a new proposal for a two-state confederation that they hope will offer a way forward after a decade-long stalemate in Mideast peace efforts.

The plan includes several controversial proposals, and it’s unclear if it has any support among leaders on either side. But it could help shape the debate over the conflict and will be presented to a senior U.S. official and the U.N. secretary-general this week.
