Ukraine at risk of becoming a 'frozen' conflict, warn U.S. officials

US officials are considering the possibility of the Russia-Ukraine war becoming a frozen conflict that could last for decades, similar to other lengthy face-offs in South Asia and the Korean peninsula. The Biden administration is discussing potential lines that Ukraine and Russia would agree not to cross, but which would not have to be official borders. A frozen conflict could be a politically palatable long-term result for the United States and other countries backing Ukraine, as it would mean the number of military clashes would fall, the costs of supporting Kyiv would drop, and public attention to the war would wane.
