Not so, my FRiend! Panama has been independent (initially from Spain)since 1821. Columbia made claims (never agreed to by Panamanians) but gave up those claims in, I think, 1903. The Canal Zone was administered by the US until it was turned over per the Carter treaty. More that you probably wanted to know about Panama history right here.
It doesn’t matter whether or not Panama was American territory or not, McCain’s parents were citizens of the United States. That in itself qualifies McCain as a natural citizen.
His father was a naval officer assigned in Panama on active duty at the time.
This also qualifies McCain as a natural citizen.
I give up.
