The US invaded Russia?

Yes - 100 years ago.

Fucking amazing what people seem to forget or aren't aware of -

In July 1918, U.S. President Woodrow Wilson had personally typed the “Aide Memoire” on American military action in Russia that was hand-delivered by the Secretary of War at the beginning of August to General William Graves, the designated commander of the U.S. troops en route to Siberia. Wilson’s document was curiously ambivalent and contradictory. It began by asserting that foreign interference in Russia’s internal affairs was “impermissible,” and eventually concluded that the dispatch of U.S. troops to Siberia was not to be considered a “military intervention.”
