In hindsight, the advent of the Euro by the EU was at least partly designed to create a new fiat currency that would vie with the greenback.
Not anticipating that a US administration would commit military crimes that would hasten the flight from the greenback as a means of weakening the terrorists through their financial support system.
Now the Euro becomes the unexpected beneficiary, along with gold probably but gold is insignificant as a store of the wealth which will be lost because there simply is not enough gold and it's useless as a negotiable instrument of exchange.
So it will be the Euro and maybe some other currencies that will rise against the greenback, while gold becomes a temporary storage of value as the greenback falls.
