To Tim, Petros et al.at IBS:
The organizers at George Mason Law School inform me that the video of the event will be posted in a few weeks. Yes, it was great to have a chance to offer a few points directly to Prof. Harvey and Jesse Eggert at Treasury. Once the video is up, we can let viewers to decide who might be a flake and who is not.
Bottom line from the event is that it confirmed my sense going in of FATCA’s extreme political vulnerability and ripeness for repeal — if financial institutions (both US and non-US) and foreign governments would stop acting as, in effect, FATCA enablers. Most significant: Prof. Harvey, Mr. Eggert, and pretty much everyone admitted in substance that FATCA as written can’t be enforced. IGAs (intergovernmental agreements) are essential for the US to implement what would otherwise be an unenforceable regime. No one pretended that FATCA could be successfully enforced solely as a unlilateral and direct U.S. imposition. Either Washington will be successful in pressuring or tricking other countries into enforcing FATCA on themselves, or the whole scheme collapses.
