That interpretation of the constitutional grant of foreign affairs and defense to the executive forbididng requiring a warrant is not obvious to me.
Do you have any case law to cite for this, or it's just your favored argument that you'd hope a court would agree with? You are talking about it like it's settled law. Cites?
Also, note that the cases you are talking about to which the law applies have someone in the USA involved in the wiretapped conversation as well. It wouldn't shock me if the courts -- although probably not the current supreme court, but you never know -- simply said it required a warrant constitutionally at some point in the future. It's certainly not obvious that you can wiretap an American without a warrant as long as they are talking to someone overseas.
