You quoted the whole thing that you apparently didn't care to read nor challenge. I'm writing it down again in hopes you'll read my whole post. The comintern organized a 50k strong army for Spain between 1936-38. The comintern organized and coordinated many hundred thousands strong partisans and resistance fighters under WW2. It did the same in 1949 China.
But let's see what you are proposing: Stalin should have risked his alliance with the Brits and Burgers and thus the existence of the only socialist revolution that didn't fail just so that maybe a revolution in India could succeed. What you are proposing is the most idiotic thing ever: risk one socialist country's failure for the mere possibility for another succeeding.
This idiotic strategy of yours AT THE VERY BEST would have resulted in a few dozen million more dead Russians (we wouldn't know because your whole idiotic ""premise"" is alternate ""history"") and a new socialist revolution in India while AT THE VERY WORST it could have meant the USSR's defeat and restoration of Tsardom and a failure of India as well - either as the next last standing socialist state (we are back to square one, you genius, a secluded pariah state having to start everything
again, the industrialization, collectivization, education, etc.), or just remaining a colony of Brittain if it failed.
This is EXACTLY the type of INSANE ADVENTURISM that Trotsky was got icepicked for.
