 Of course, the example that came immediately to my mind when I heard about the potential for North Korean troops to go to Ukraine was Angola in Africa in the 1970s. In the midst of their communist revolution, Cuba sent many troops there. And so it wasn't the Soviet Union intervening directly. It was instead the Cuban proxy. So I think we could see something similar. But it is true that this is just a few stories and we haven't had any concrete proof yet.
