At a time when the modern international order appears under strain, it is tempting to look back and ask what we can learn from the 1945 San Francisco Conference that created the United Nations. Such nostalgia is misplaced. The 1945 order failed—not partially and over the long term but completely, almost immediately, and with terrible consequences. It is its failure that holds lessons for us today.

A new world order needs new institutions:

"The San Francisco Conference was the culmination of American post-war planning. It was based on the notion that the old balance of power system had failed and needed to be replaced with a cooperative system. The major powers would work in concert at the United Nations to confront aggressor states and to peacefully resolve disputes between themselves. 

There was also a second more realist logic underpinning this lofty vision. Each of the victorious powers would be granted a sphere of influence that the others would respect—the Soviet Union in Eastern Europe, the United States in the Pacific, and the United States, Britain, and France in Western Europe."
