I'll go so far as to say that Israel's 1948, 1967 and 1973 wars are the quintessential examples of how to win a multi-front war. In all three, they leveraged superior air power to great effect and emphasized concentration of force, defeating enemies in turn. I suggest Michael Oren's Six Days of War and Abraham Rabinovich's The Yom Kippur War for readable, fascinating histories of the latter two conflicts.
