U.S. Secretary of State Antony Blinken signaled on May 31 that President Joe Biden’s administration has ratcheted forward support for Ukrainian military activity to deal with threats inside Russia’s borders but offered few specifics about the changing rules of engagement.
Throughout the more than two years of large-scale fighting between Ukrainian and Russian forces, the Biden administration and other leaders of the NATO countries have gradually provided the Ukrainian side with more advanced and longer-ranged weapons systems, gradually considering and then reconsidering how much they can help the Ukrainians without escalating into an open conflict between NATO and a nuclear-armed Russia.
