Not surprising. Dual nationals are warned that the U.S. is limited to the assistance we can provide when they are in their other country.
We should eliminate dual nationality. Either you are an American or you are not.
That already is the law in the USA. The issue here is about people traveling to other countries. If you are a US citizen then you are still subject to the laws of other countries if you visit those countries. You aren’t forced to visit those countries.
