This is the introductory cinematic of Command & Conquer: Red Alert 3. I played the heck out of Red Alert 2 as a kid, but this is a blind first play. On the verge of defeat, the Soviet Union makes a desperate gambit, employing an experimental time machine to change the past... with unforeseen consequences.
