That's.... complicated. Suffice it to say, the US was not allied with the Tsarist regime, and Kerensky's offensive petered out way too quickly for the Russians to be a major contributor to the Allies after the initial revolution. The United States severed diplomatic ties after the Bolsheviks took over. So the US was allied with Russia for about half a year.
