So, we broke our promise to a no-longer-existent entity...
I guess that we should also feel guilty for all the broken promises we made to the Ottoman Empire.
Regards,
I can't think of a single other historical example of anyone even trying to make that argument before. When Dubya refused to abide by the terms of the Kyoto Protocols signed by Clinton, nobody said "you can't do that.". When Trump rejected the Paris Agreements signed by Obama, nobody said "you have to abide by it because Obama promised." But now, we have all these people coming out of the woodwork to say the nation is bound forever by a verbal promise made by the Bush Administration in 1990.
It's just weird.
Speaking of entities that no longer exist, try the government of Ukraine that died in a coup in 2014. Whatever agreement was made with Ukraine died in the coup.
