I don't think that Snow/AG can control the dollar except for very short periods. They can try and "talk it" up or down, but Japan has shown that this is an exercise in futility. The dollar will reflect a number of competing processes, the two major one are our balance of payment deficit and the relative health of our economy vs the economies of the rest of the world (ex China as long as they keep that peg). This right now indicate (both fundamentally and from the technical picture) that the dollar is in the process of strengthening against the Euro, and this process may continue until there is better visibility that "old Europe" found a way to revive their economies without going into budget deficits greater than prescribed by the ECB (I believe it is 3% of GDP). The US does not have that constraint (our budget deficit this year will probably exceed 5% of GDP), and thus can stimulate its economy better than "old Europe"can and that will cause strengthening of the dollar, if for no other reasons as to not exacerbate the economic problems Europe has.
