“Dear Mr. Cruz, it’s unconstitutional to strip citizenship from a citizen. You know that. Your proposed law is a non-starter. What we do with those who join ISIS, is try them for treason.”
Not true. Please refer to your U.S. passport, which states that you can lose your citizenship by joining a foreign army. Which is a signed document, by the way.
Please refer to the statute referred to in the passport. Don’t overlook “with the intention to relinquish US citizenship” part.
I had a thought on this this morning. If that rule applied literally, if joining a foreign army strips citizenship automatically, then joining a foreign army cannot be treason. The notion of prosecuting an invading army for treason is nonsense, they are enemies, yes, but none of the non-citizens (owing no allegiance to the US) among them is committing treason against the US.
