True the weaker USD will help with the US recovery. But it also hurts holders of US treasuries who are funding the US deficit. And eventually it imports inflation into the US economy. So eventually to correct the imbalance US interest rates will need to rise, which will strengthen the USD. This will not occur until well into 2010 though. Watch more closely for USD intervention vs EUR and JPY once they get cranky that the high EUR and JPY are hurting exporters and growth from Europe and Japan.
