Are we talking goods, or deficit? If you mean 600billion deficit, then remember that this includes investments the US is making in other countries, as well as the costs of military actions abroad. This is all included in the balance of payments.. . Profits from investments abroad, in the long run, will help lower the deficit. Most countries in the world (and their currencies) depend on a stable US dollar, it is this interdependency that will help the US in case there is ever a problem with the economy in the near future (highly unlikely).
