If someone wants to trade with Turkey or the UAE, they are free to do so. I admit I'm not current on the most recent sanctions list, but as far as I know, both those countries and companies aren't on it.
On the other hand, suppose they are. Why should it be a given that we trade with whatever country? I'm asking this honestly because I've seen that argument thrown around a lot lately. As in: "the EU should buy Russian gas because it's cheap"... Well, no we don't. We can buy it from whoever we like.
We absolutely have the right to draw moral lines in the sand: if you do business with brutal dictatorships, you are the enemy too.
Why is the US doing business with Saudi Arabia? Let's see how your moral lines bend around the agenda.
This is playing out right now in the EU in Switzerland and Germany with allowing armaments to be re-exported to Ukraine. [1]
