Let me approach this from a different angle. If a military defeat is necessary to create revolutionary conditions, is it not then in the best interest of the working class in each imperialist power for the other to win, and does that not then put the working class in each imperialist power at odds with one another?
Don’t you believe in internationalism? Solidarity?
How many hundreds of thousands of lives does it cost to create revolutionary conditions, and how can you be so arrogant as to cheer while they’re fed into the meatgrinder, believing with such certainty that it means you’ll get your chance at revolution?
This is a non sequitur. It doesn’t follow that Allende choosing reform over revolution is what resulted in the US interference. The US has been known to interfere in revolutionary movements as well.
