The project director on Israel-Palestine for the International Crisis Group, an independent non-profit focused on preventing and resolving deadly conflict,  Max Rodenbeck discusses the Crisis Group's recent report on the Gaza Peace Plan advanced by President Trump. He describes how Trump's 20-point plan developed, its unavoidable ambiguity, the many questions about  the ceasefire's terms and prospects, and what will be needed for the plan to succeed. He notes sustained engagement by other countries, and above all by the United States, is a must if  the plan is to advance beyond Phase I. If it doesn't, Palestinians in Gaza will be left in an indefinite humanitarian nightmare, unable to reconstruct their homes and their lives.
