Irrespective of one’s position on the policy statements of Donald Trump, or the views held by David Friedman, I think there is a broad mis-fire in Mr. Brownfeld’s argument.
The selection of US diplomats to foreign posts belongs to the President and the Secretary of State. It is subject to review by Congress. By convention, and out of respect, the government receiving the ambassador, (in this case, Israel), is typically consulted prior to to the selection and vetting process.
The notion that a US Ambassador to Israel must also be approved by the Palestine Authority or Jordan is strange. And the thought that the selection of Mr. Friedman somehow fuels Da’esh is over-the-top.
Is Mr. Brownfeld suggesting that Mr. Trump place a phone call to Abu Bakr al-Baghdadi to negotiate a list of agreeable US Ambassadors to Israel? Even if the Trump team had renewed Daniel Shapiro’s contract, how would that have reduced ISIS / Daesh animosity against Israel, Jordan, or the Palestinian leadership?
