KindHearts for Charitable Humanitarian Development v. Geithner and Al Haramain Islamic Foundation v. U.S. Department of the Treasury
Those are names of cases, not laws.
Precedent fills out the finer points in how laws apply, or don't.
Perhaps you’re not familiar with the common law system and its reliance on case law?
In both of those cases the designated entity was incorporated in the US (KindHearts in Ohio, AHIF-Oregon in Oregon).
I didn't say it was illegal.
That's more of a problem with the US code of law than with the point GP is making.
I have 0 issues with the US sanctioning criminal organizations that are defrauding Americans. It’s not a slippery slope, it’s common sense which is why literally nobody is trying to defend the perpetrator in a court of law.
