- Russia is waging an (illegal) war of aggression -its war aims are almost certainly not limited to annexing Ukraine - it is therefore sensible for the West to stop Russia in its tracks now, and force Russia to withdraw its troops from all of Ukraine including the Donbas and Crimea so that aggression is seen not to be rewarded - those who claim to worry about WWIII are largely pro-Putin activists, which is to say they support rape and torture as a means of aggressive warfare and should be held in contempt accordingly - there is zero evidence that Putin is willing to risk WWIII as it would (obviously) result in his annihilation. - delaying the supply of tanks, aircraft and long range weaponry simply raises the cost in lives and treasure of removing Russia from Ukraine. - whatever cost the US has incurred in military supplies it has recouped twenty fold in increased LNG revenues.
