>Oh, and targeted sanctions - aren't. Entities will view any sanctions as a legal risk and find it easier to just stop trading with the country at all. See Iran with medical supplies during the pandemic. The sanctions on Iran aren't targeted. They're blanket sanctions with specific exceptions. The problem there is asking international companies to do a bunch of stuff otherwise forbidden by the sanctions (financial, logistical, etc) which I assume is either a pain to get approved ahead of time or frightening to justify after the fact. A better example of targeted sanctions is what's happening in response to the poisoning of Navalny. Specific Russians were sanctioned. That doesn't hurt uninvolved citizens nearly as much.
