The issue is that the restrictions imposed by the US government on banks are so constraining that many countries with a lot of corruption would just be cut out of the whole world banking system. This would be a death sentence for these countries as most of them are doing poorly already economically. In addition, it's not like the US itself is without corruption but because they're the one who make the rules, they don't apply to their own corrupt entities...
