New Currency World Order

A year ago US Dollar was weak against Euro, Great Britain Pound and even the Canadian Dollar. It was string against Japanese Yen. With the recession commodity prices plummeted. High rising Euro and ever strong GBP started to weaken against US Dollar. Yen on the other hand started gaining against US Dollar. A strong US Dollar is good for inflation, but bad for earnings of multinationals. Americans can take a trip to Europe and Australia without having to spend an arm and a leg. Is this new currency world order good? What will happen if the proposed $850 billion second stimulus package is enacted?
