I say, instead of sanctioning, use tariffs. Let them pay 150% and just siphon the money that way. At least on some products.
150% plus tariffs. Whatever pays for 10 drones.. minimum. No flinching on getting our money back and thanking them for the other 9 that will be flying over them.
Next shoot down multiplies the sanctions/ tarrifs x 100. Put France n SA on notice also.
