It's simple but very difficult. The simple way is to force Russia's hand to remove their military, their equipment, and their financing of the—quote, unquote—“separatists”, because at the end of the day, as I mentioned at the very beginning, there was never a separatist movement. This was completely engineered, financed, operated, and organized by the Russian Federation, by Vladimir Putin and his lieutenants. The reality is that the people who have led those movements are Russian citizens, Russian military and intelligence officers. Once those people are removed, then you can bring peace and stability to that region.
