My experience is that unless it is the specific borrower who defaults who also has assets overseas, then it is very difficult (as it should be)under US and international law to seize that property. If a Government defaults, it is hard to justify that you can seize some prince's real estate in London. Although given the interconnection between the Government purse and the royal family it would be a stronger case to make.
Yes. And I would expect that if a default takes place, and the Saudis are in "the doghouse" over their terrorist support role, the case would be even stronger.
