not really, if you actually study history as is, taking into account the actions and politics of the time, and not just eat up shit from a school book, then you'd know that: 1. russian empire was eager for a war with austria-hungary as a way to quell revolutionary shit in its society and to redeem its image after the russo-japanese war fiasco. to cause that war they've pushed serbians for anti-austrian chimpouts. they just didn't expect for germany to get involved and steamroll them. also, it was russia whom announced mobilization and declined stopping it, basically forcing germany's hand to step in as well.  2. soviet union created the modern wehrmacht and luftwaffe during 1920s and 1930s, doing training and military development with germany. then it also supplied germany with resources for war up until 1941. it also secured germany's flank, allowing germany to attack on the western front.  without russian involvement neither of the world wars could even happen. simple as.
