"Let's wipe out Ireland's economy" might not be the best angle to solve the issue. It's quite silly, since the EU would probably benefit from a uniform corporate tax rate and closing loopholes that allow the "double Irish". The EU could then afford to compensate the relative loss in Ireland (and a few other places). But this would require moving forward to a federal EU, with a bigger budget and a much greater effort at tax harmonization. Not a very popular idea these days. I think it makes sense that a few countries start on their own, especially big ones (France, Germany, ...) We'll probably see some retaliation against big EU corporations, especially in the US. But I don't think anybody will shed a tear.
