US sanctions mean if you trade with the santioned org.. YOU get sanctioned (lose access to trade or financial systems controlled by US or US companies like Visa)

If you donate to them from the US, you probably get put on a no-fly list at a minimum. Maybe even a friendly visit from the feds at your home!

They will become pariahs financially speaking. Nobody will be authorized to wire money to/from them. It's brutal.

Anything between having their google profiles deleted to abducted and tortured at a CIA blacksite.

  • Relationships with non-U.S. providers frightened by American secondary   sanctions.
  • Access for people in the United States who currently use A/I’s services.
