The article says images over Iran are still available without delay. It’s the regions around around that are affected. I assume it is to hide the effectiveness of Iran retaliation to Iran or to public opinion.

I don’t believe the people who contract them are being duped though. They do it to delegate and dilute the chain of responsibility until their decisions become acceptable.

the State Department no longer proactively attempts to prove such intent, and issues a Certificate of Loss of Nationality (CLN) only when an individual “affirmatively asserts” their relinquishment of citizenship.
