Very interesting article, although I don't understand why you have to be "anti-Islam etc." to appreciate it. What's "etc."?
I think it's a very false dichotomy to propose Shia = bad and Sunni = good, which the article almost manages to avoid. Iran and it's 'associate' Hezbollah are to a fairly large extent the best hope Shia muslims have against the Sunni parties of Saudi Arabia, UAE and their 'associates' USA and Israel. Hezbollah was and may still be, the most effective social welfare organisation in Lebanon, whose neighbours (particularly the one to the south, have consistently de-stabilised since 1948 (although you could go further back), which is briefly acknowledged.
I can't see what was in Obama's administration's mind if they did pull back (as seems to be indicated) the RICO prosecutions - if it was only for the nuclear agreement it seems rather a flimsy reason. It raises the question of the funding of Al Qaida / Daesh - which is not discussed under this article - how different is that? I'm not throwing a red herring into the pot, I'm just interested - a lot of people who I wouldn't have thought of as silly, business people - believe strange things about that (my personal anecdotal testimony from a couple of years ago) - and they weren't referencing Hezbollah, nor did the politico article.
In light of the reference to Latin America, a roll-call of US black ops and drug funding along similar lines would be a fitting book-end for the article you reference, doncha think? There's a lot that can be done with money.
