In regards to SOIC, Lenin made his stance quite clear even before J.V Stalin came up with the entire concept of SOIC.
“I know that there are, of course, sages who think they are very clever and even call themselves Socialists, who assert that power should not have been seized until the revolution had broken out in all countries. They do not suspect that by speaking in this way they are deserting the revolution and going over to the side of the bourgeoisie. To wait until the toiling classes bring about a revolution on an international scale means that everybody should stand stock-still in expectation. That is nonsense.”
– Lenin, Speech delivered at a joint meeting of the All-Russian Central Executive Committee and the Moscow Soviet, 14th May 1918, Collected Works, Vol. 23, p. 9.
