The Germans had Race Cars with 500HP and 200MPH top speed in 1937If you think like that, the war is a Revolution against Eurocentrism and it started in America with the destruction of European empires. Then the fire spread to France, then Napoleon crushed the revolution, but it flared up again in different parts of Europe, the turning point occurred after the Hungarian revolution, then WW1, where the revolution won, and the roaring 20s came. WW2 was a revenge and it ended with the victory of the counter-revolution. The totalitarians were in power. By 50s, they somehow managed to be eliminated after the McCarthy purges. This war never ended.
Napoleon did not exactly start anything, he acted in response to the destruction of the bastille and the collapse of the Old Order.
