US President Donald J. Trump’s Gaza plan could change the nature of the Gaza war and prolong rather than end the hostilities.

Amid calls for a unified Arab response to Mr. Trump’s plan to resettle or ethnically cleanse Gazan Palestinians, according to many Middle Easterners, officials, journalists, analysts, and social media activists are mulling options.

The options under discussion range from approaches that would give US companies a significant stake in Gaza’s reconstruction to the fuelling of a Hamas-led armed guerilla-style resistance.
