Glenn Hubbard is delusional if he thinks "The Promise Of Trump's Mideast Plan" [1] will be successful. The Marshall Plan worked because the recipients of the aid were willing participants. The Palestinians not only refuse to accept the aid plan but imprison and harass Arabs willing to listen to the Trump proposals. The Marshall Plan assisted capitalist nations to rebuild after World War II. In the Middle East we are dealing with ideology and religious fanaticism far more powerful than economic needs. We made this mistake in Iraq and President Trump is making the same mistake. Many in Israel also believe that economic needs will rule over religion. The 19 hijackers on 9/11 were middle- to upper-class Muslims. Poverty didn't motivate their attack on New York and Washington.
While the economic conditions in Gaza and the Palestinian territories are a disaster, financial assistance won't bring peace, and more likely will be used to fuel more terrorism.[2]
