President Trump is doubling down on a bet that diplomacy with Iran will produce a deal that ends hostilities there. Yesterday, he vehemently insisted that Israeli Prime Minister Benjamin Netanyahu forgo further attacks on Iran’s foreign legion, Hezbollah.

Mr. Trump appears to be heeding the advice of U.S. advisors like special envoy Tom Barrack and putative allies like Qatar and Turkey. 

They previously persuaded him to engage with another sharia-supremacist regime in Syria at the expense of actual allies there among minority communities. 

The result is instructive: Ongoing, murderous jihadist attacks and the prospect for outright genocide – not peace. 

Diplomacy with sharia-supremacists only produces hudnas – temporary pauses that allow them to rearm, regroup and renew their jihads under more favorable circumstances. 

Give peace its only chance, Mr. President: There is no substitute for decisive victory.
