So to your question: Yes, it was impossible to sue a sovereign nation in the US. Both US and international law prohibit it.
What I know of US law is gleaned from TV, but it is clearly not the case that international law prohibits suing a sovereign nation, since it is permitted everywhere in Europe, as I pointed out in the last post, and it happens. The European Convention on State Immunity, the draft UN convention on the same and the UK State Immunity Act all contain a very similar list of exceptions to State Immunity - amongst which is injury or death to persons or property damage.
A quick glance at the US Foreign Sovereign Immunities Act reveals that it also contains an almost identical list of exceptions. Foreign states are not immune from lawsuits in the US when:
quote:
money damages are sought against a foreign state for personal injury or death, or damage to or loss of property, occurring in the United States and caused by the tortious act or omission of that foreign state or of any official or employee of that foreign state while acting within the scope of his office or employment
Note that the US law, unlike the European convention, does not require that the actionable act was committed on US soil, so it seems clear that US law already permitted the Saudi government to be sued if they were, indeed, liable for 9/11.
Until now for this reason. And if we can do it on our end, what's to prevent Japan from suing us for the atomic bomb? Or Iraq for our invasion?
That question has been addressed following a series of lawsuits in Italy and Greece against the German state for activities committed during World War II. The International Court of Justice ruling on the case decided that actions committed by an armed force during wartime are clearly a separate case, or warfare would not be possible. I'll leave it to you to decide if that would be a good thing or not.
