In a rare lucid moment in January 2016, then-Secretary of State John Kerry admitted that the Tehran regime would use some of the funds from the Iranian nuclear deal to fund terrorism.

“I think that some of [the money] will end up in the hands of the [Islamic Revolutionary Guard Corps] or other entities, some of which are labeled terrorists,” he said in the interview with CNBC in Davos. “You know, to some degree, I’m not going to sit here and tell you that every component of that can be prevented.” It’s worth watching footage of the interview to observe Kerry’s nonchalance as if the possibility of transferring money to some of the world’s most lethal terrorist groups bothered him not in the least.

Flash forward more than two years later, and Reuters reports:

Germany’s federal prosecutor on Wednesday remanded in custody an Iranian diplomat suspected of having been involved in a plot to bomb an Iranian opposition rally in France but said the suspect could still be extradited to Belgium.

Belgium is already investigating two Belgians of Iranian origin arrested earlier this month for plotting an explosive attack on the annual “Great Assembly” of Iranian opposition exiles last month on the outskirts of Paris.

In a statement, the German federal prosecutor said the Austria-based Iranian diplomat is suspected of commissioning a couple living in Antwerp to carry out the attack and providing them with a detonation device and homemade explosive TATP.

Mercifully, European security forces unraveled the plot before the attack took place. But imagine if they had failed. Imagine the blood spilled and body parts scattered outside a rubbled convention center in Paris; the smoke rising high above the densely populated urban core of the French capital. Now think back to Kerry’s arrogance and indifference to what it would mean for the U.S. and its allies to grease the wheels of Iran’s terror machine.

Say what you will about President Trump’s penchant for hyperbole, but his characterization of the Joint Comprehensive Plan of Action–“the worst deal ever”–was spot on.
