The only way to avoid such a catastrophe — a pre-emptive strike. For example, the default on the dollar!
… For the week the dollar decreases in value in three, five, even ten times. Such a move will destroy hundreds of millions of people around the world, will cause damage to the world economy, which is comparable to the damage from the war.
In the U.S., this is partly weaken national disaster, it will be able to shift the costs to other countries.
But, most of all, such a scenario would lead to chaos, a new division of the world … And in "peredelennom" world space to the U.S., most likely will not. Be a new political system … After the First World War, there was the Versailles system … After the Second World War — the agreement in Potsdam … New Versailles and Potsdam will not be kind to the United States.
Possible and a new Nuremberg for the main perpetrators of the economic collapse. But even without such troubles new world order will emerge without the U.S..
