Why did the original Terminator have an Austrian accent? Perhaps because he was constructed not by machines in a distant future, but — as in this diorama series — by the Russian military during WWII... for a very different mission.
A toy hobbyist known on the Toyster.ru forums as Aquila painstakingly created a step-by-step photo series of Russian men in World War II uniforms, assembling a T-800. As the sign in the final few pictures indicates, the T-800 has orders to travel to Berlin, and, unless John Connor had an ancestor hanging around the Nazi stronghold at the time, this T-800 was probably built (and perhaps traveled back in time) to kill Adolf Hitler. Of course, we know that never actually works.
