The Biden administration has approved supplying Ukraine with American anti-personnel mines to counter Russian attacks, as Ukrainian defenses in the east weaken. This decision follows Ukraine’s use of longer-range American missiles against Russia, escalating tensions. In response, Russia has lowered its nuclear weapon use threshold. Defense Secretary Lloyd Austin stated the U.S. decision was due to Russia’s increased use of foot soldiers, necessitating measures to slow their advances. This move is part of recent efforts to support Ukraine in the final weeks of Biden’s presidency.
