There has to be some kind of way for the US military to be held responsible for their actions. If they kill someone who was innocent, the family should have some way to be compensated. Otherwise there is no accountability in the military. If everyone is faceless and there are no reproductions, thats how immoral things happen.
Military action that takes the lives of innocent civilians is abhorrent and someone needs to be taken accountable for such heinous crimes. It is not common for a foreigner to sue the U.S. for military action but this seems to be a good step in the right direction to right the wrongs that have been committed to innocent civilians not involved in the war.
The United States does not exist in a vacuum. Our military actions have direct consequences all around the world, both for the people on the ground in the affected area, and also for the governments who may also have a presence there. This means that foreign factions should be able to retaliate as well.
Foreigners should not be allowed to sue the United States for military actions. These unfortunate events occurred during the acts of war. There have been many innocent Americans killed in conflicts, and their families were never allowed to sue foreign governments. The United States shows great restraint in fighting wars when compared to other nations.
