I do consider that in some cases they have no problems abusing laws of other nations. The countries you mention are very small. They could not accumulate the wealth they have in a vacuum. One thing small "banking" countries have subsided on for ages is helping people/companies in other countries hide their money. If these small and noble nations are indeed noble, they will find a way to survive without doing this. They already have a head start. If we cut them off now, will they be able to survive as they have without continuing to engage in illegal banking? Or how long will it take them to devolve into banana republics?
