North Korea’s Kim Jong Un vowed “full and unconditional support” on Wednesday for Russia’s Vladimir Putin. The two leaders held a summit that the U.S. warns could lead to a deal for North Korea to supply Russia with ammunition for its war in Ukraine. The meeting at Russia's spaceport underscored how their interests are aligning. Putin is believed to be seeking North Korean stockpiles of aging ammunition and rockets, while Kim is believed to be seeking Russian help in developing military reconnaissance satellites. Russia would be violating international sanctions if it buys arms from North Korea, or provides it with rocket technology.
