This is an instance of high-flown phraseology with which Trotsky always justifies opportunism. A “revolutionary struggle against the war” is merely an empty and meaning less exclamation, something at which the heroes of the Second International excel, unless it means revolutionary action against one’s own government even in wartime. One has only to do some thinking in order to understand this. Wartime revolutionary action against one’s own government indubitably means, not only desiring its defeat, but really facilitating such a defeat. ("Discerning reader”: note that this does not mean “blowing up bridges”, organising unsuccessful strikes in the war industries, and ·in general helping the government defeat the revolutionaries.)

You agree that NATO/US is perpetuating a proxy war against Russia correct? You live in a NATO country/US? Then it's your duty "really facilitating such a defeat [of one's own government]". That means organizing successful strikes in the war industries and stopping ammo/weapon shipments and raising a stink against money going to Ukraine. It means pointing out the Ukrainian Nazis and desiring their DEFEAT as our own proxies.

I suppose it doesn't truly matter whether you "critically support" Russia or not, as an American or westerner - in that your prayers won't materially empower either side or have any outcome (as long as your still organize against support/weapons for Ukraine with the rest of the revolutionaries). However, when we are having discussions amongst ourselves what good is it to all lie and pretend like we don't want Russia to win? We do, it's in our best interests. I think a lot of westerners just aren't ready to make the final leap to a full revolutionary position - just like many in the 2nd international couldn't and the SPD voted for war bonds to support their own imperialist government, breaking solidarity with the proletariat of other nations. Russia winning is the best outcome though for revolutionaries in the US and across the globe, destroying the hegemonic empire is a necessary pre-requisite step to any revolutionary activity anywhere. AmeriKKKa must be destroyed and Russia is the one doing the most damage to it currently.
