Takes a bit of gambling of the first turn. If it doesn't go as planned, start over:
Turn 1:
You hit Ukraine 2v1 and 4v2 on Middle East
Turn 2:
3v1 on Ukraine, 4v2 advancing toward him
Turn 3 and 4:
Maximum armies advancing toward him. With really bad luck you might fail to advance on turn 4, if so just start over.
Turn 5 (two attacks)
Turn 6
