Secretary of State Antony Blinken warns that North Korea is benefiting from aiding Russia in its war against Ukraine by potentially aiding Pyongyang's nuclear development, posing a threat for Europe and Asia.

European governments and the U.S. have so far denied Kyiv permission to use their weapons for long-range strikes into Russia. Moscow has said such a move would be treated as tantamount to their direct involvement in the conflict, raising fears that it would open them up for retaliatory action.
