Idea for a worldwide communist event

[unmerged(137190)]

I was wondering, would it be possible to make an event where if any country in the world has a revolution and becomes a proletatrian dictatorship or if a communist party comes to power, an event could fire, provided that russia has allready had a communist revolution (bolshevik, menshevic, or communist revolution through rebels takeing the capital) and is currently communist, the the country in qustion would have the choice of entering into an alliance with russia with no expiration date (though it could be dissolved mannualy). Like an early version of the warsaw pact? Would this be possible? How would I go about making it?

Yes it would be possible. Personally the way I'd do it is as follows:

In the revolution event which turns you into a proletarian dictatorship I would include a command which activates a flag. There would then be an event - which would be classed as an invention - where this flag is a trigger condition (along with the USSR being communist). You would then get a choice to join an alliance with the USSR.
