NATO could have done more to arm Ukraine to try to prevent Russia's invasion in 2022, the outgoing head of the Western military alliance said in an interview released on Saturday. "Now we provide military stuff to a war - then we could have provided military stuff to prevent the war," NATO Secretary General Jens Stoltenberg told German weekly newspaper FAS. Stoltenberg pointed to the North Atlantic Treaty Organization's reluctance to provide weapons that Kyiv had asked for before Russia's full-scale invasion because of fears that tensions with Russia would escalate.
