* Should the US government be able to dictate the laws of foreign lands, in order to satisfy its own choice of tax regime?
No they should not. But this is not what's happening here. The transactions originated in the U.S. by and through U.S. entities.
* Should the US government be able to dictate that foreign corporations provide data to the US, forcing those foreign corporations to bear the costs for enforcing the American tax regime?
Again, that's not what's happening here. When UBS or any other foreign bank operates in the U.S., it is incorporated as a U.S. entity and must follow U.S. laws. UBS and such have chose to say "oh, those customers we acquired in the U.S., well, that data is back in Switzerland, and we have strict privacy laws there, so no can do". Sorry, but the transactions originated in the U.S. through the U.S. operating entity, Swiss laws have no say here.
These banks have gotten off incredibly light. The U.S. has plenty of existing laws on the books to allow them to seize the assets of the entire bank for their illegal behavior. The only reason they did not is because seizing Swiss banks would have unknowable repercussions from global elite.
