I have been planning on doing the "right" thing and buying ETFs domiciled in somewhere like Ireland using a broker not in the US and so avoid having to pay US estate tax. I do take a penalty in the ER and in the diversity of funds available. So, maybe I shouldn't care about the estate tax? Would you? Is the US going to clamp down? How could they? Register all deaths world-wide?

Under U.S. tax law, the estates of foreign holders of U.S. assets, such as stocks, real estate, or valuables, are required to pay estate taxes on those assets after the death of the owner. There's even a handy piece of IRS paperwork — form 706-NA — to help calculate the tax.
But one veteran Swiss banker tells CNBC that this rule is widely ignored around the world, and the U.S. government has no way to know how much money it is owed under its own laws.

Despite that, publicly available statistics from the IRS show that very few foreign citizens file estate tax paperwork. According to the agency's data, just 849 people worldwide filed nonresident alien estate tax returns in 2014, paying just more than $60 million in net taxes to the IRS.
Those figures pale in comparison to the breathtaking scale of U.S. assets owned by foreigners.
