When the U.S. Department of Defense (DOD) halted the transfer of critical air defense missiles and other weapons to Ukraine, Kyiv and its partners were caught off-guard and are now left scrambling for clarity on the scope and length of the Trump administration's decision.

The Ukrainian foreign ministry called in a top U.S. diplomat in Kyiv to discuss American military aid to the country, after the Trump Administration scrapped a planned weapons shipment because of concerns about its own diminishing stockpiles.
