The strength of the USD is artificial and comes from the fact that other nations need the USD to trade due to the Bretton Woods agreement. Without the demand from other nations, USD would have collapsed long ago due to the debt. In other countries, when they print currency to cover their debt, it results in inflation. With USD, the downward direction of USD due to inflation is offset by the upward direction of USD due to demand from other countries.
Either you're a currency trader shorting the dollar and playing his book or you don't know what you're talking about.
