“The Russian invasion was stopped by a relatively small amount of western aid, himars and 777, javelins and a small amount of air defense checked Russian advances and resulted in Kharkiv and kherson successes.”
Your timeline is way off. Those weapons didn’t show up until long after Ukraine stopped the Russian attack.
Got me, dropped, with help from javelins, 777 and himars arrived and Kharkiv and kherson happened after their arrival
Stopped and pushed back okay
Still my point stands, a relatively small number of western weapons allowed large reversals of Ukranian territory taken by Russia
