I would say no. I would be quite dismayed to see a list of countries that would be exempt. In part, it relates to the answer to your previous question about why those countries, those four in particular, in the U.S.... My understanding is that the amendment to the Foreign Sovereign Immunities Act in the U.S. was in connection with the new anti-terrorism legislation after September 11. Those countries were on the list of state sponsors of terror. That was the particular interest of the U.S. in creating this exemption.
It would be very unfortunate to politicize the process in the same way, to decide ahead of time, for example, which countries would be most likely to commit atrocities. That, of course, changes, depending on changes of governments and developments.
