The US needs Stingers to defend either themselves or a current NATO member exactly how?
Because clever replies like "got news to catch up":
Hint: neither the US or NATO members are directly involved in the war between UA and RU, or any other war (yes, the US is always at war with other nations.)
US giving away billions in equipment for a foreign actor and thus creating the need to replenish stock is all on them.
Funny to think what the US will gain tru this meddling in European affairs by though talk and providing billions in support to Zelenskys regime: even more bases outside their jurisdiction to further their global dominance, and the ones on Ukrainian territory lie right next to Russia. MAJOR gain. And on a second note ofc increased TAM for their products and services, fuelled by Ukrainian indebtness.
