Yes... US "only" financed, coordinated, and offered active military support for the invasion. Then imposed a blockade on Cuba for asking for nuclear help from the USSR.

And in 2014 forces which were definitely just pro-Russian militias as they clearly had no Russian insignia invaded Crimea the moment Ukraine started contemplating a relationship with the West/EU.

This kind of rationalization or nit-picking in order to reach the conclusion you had already settled on has no value, just because there are sides doesn't mean you have to blindly take one. Education and critical thinking help.
