I will confess it is a complete and total mystery to me where this belief comes from. That isn't to sneer. I simply cannot fathom this blind, utter faith in some mystic French diplomatic revelation that is seemingly so absent a shred of real-world evidence.
What we got from the multipolar Great Powers geopolitical alignment was colonial exploitation, arms races, brinksmanship, World War One, and the fall of its major participants in the forms of the Romanov dynasty, the Hohenzollern dynasty, the Habsburg Empire, and the Ottoman Empire. I am a bit at a loss as to why this is considered preferable to the current unipolar configuration. Are we not killing enough people? Is that the problem?
We are not kow-towing sufficiently to the glory that was France...way back when.
The French invented diplomacy, y'know.
Took all the mess out of surrendering...
