In the U.S., yesterday presidential candidate Rick Perry proposed slashing the tax level of repatriated offshore profits. "He would allow multinational companies to repatriate profits earned overseas at a 5.25 percent rate and would set up a territorial tax system that essentially ends U.S. taxation of profits earned outside the country."
This would surely boost the economy in the U.S. But once again, the benefits seem limited to large multinational corporations (i.e., large donors) rather than to everyone. So, I am not sure whether that would help you, but it is a good idea to wait until after the election. There is also the chance that the Republicans might repeal FATCA, as there is a push to do so by U.S. expatriate advocacy groups.
Otherwise, you need to hire a very good tax attorney. Be sure to hire a tax attorney, not a CPA or another tax specialist, so that you have attorney-client privilege. If you decide that the cost to repatriate your money is too high, your privacy remains intact.
