What he is trying to say at least I believe is that the strategies will always focus around capturing VC. He prefers creative strategies where VC are unimportant and the idea is to knock out your opponent. The problem in his logic is that this is a historical game and historically there were certain cities that were essential to winning the war. Capturing Paris won the war against France, the German failure to take Stalingrad was a turning point in the Eastern campaign, so on and so forth. While I can understand his point the fact is that the victory cities are located in the strategic centers (for the most part) even if there were no VC in them those are still the territories you would want to attack and take over so it kind of makes the arguement null and void.
