NATO has urged Europe to boost defense production to secure its borders. NATO Secretary-General Jens Stoltenberg emphasized the need for increased defense budgets and higher production of military equipment. He stated, “We must spend more to keep ourselves safe.” He also pointed out that the production of military supplies has been insufficient. After the U.S. halted military aid to Ukraine, its effects are already visible, as Russian forces have surrounded thousands of Ukrainian troops in the Kursk region.
