The US is already forcing a lot of countries to follow their stead, to the point that the US is now one of the world's best tax havens to park illicit cash. With the Double Irish sandwich being shut down, I can only see more internal schemes being developed within the US - corporations aren't rushing to park gains in Seychelles or Guernsey. The point is that the US needs to find a balance between taxation and good business, kind of like Switzerland in the EU (although I agree, both are different ballgames altogether). The way I see it, there's a triangle here with three vertices to balance against - business pragmatism, optimal taxation and regulations for private markets.
