Answers to your questions:
"I've heard international calls only then it was international calls terminating in the U.S., then it was international calls originating in the U.S."
Yes, those are both international calls. They both involve signals traveling into the United States. If something foreign is invading your territory you have a right to inspect it.
"Where in the Constitution does it say that?" (that the president has the right to examine these international phone calls).
You really should read it for yourself.
Article II, Section I.
"The President shall be Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States, when called into the actual Service of the United States;"
"When called into actual service," see. And when were the armed forces called into service?
Go back to 2001:
"Resolved by the Senate and the House of Representatives of the United States of America in Congress assembled,
...
That the President is authorized to use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001, or harbored such organizations or persons, in order to prevent any future acts of international terrorism against the United States by such nations, organizations or persons."
"All necessary and appropriate force." Got a problem with that? Talk to your elected representatives and senators.
I guess that also answers the "Who gets to decide who is a terrorist?" question.
This "debate" is settled in my mind. But I'm tired of always being on the defense. It is time we go in the offensive.
Non-Sequitur, please tell me what law, specifically, you think President Bush broke? I don't want to hear any, "Well, I don't know, but I'll leave that to an investigative committee."
Give it your best guess.
The section that text appears under is titled "Authorization for Use of United States Armed Forces." It says nothing about wiretaps or the NSA.
An excellent question. So many of the kneejerk civil-rights absolutists have made the assumption that warrantless wire taps are unusual or totally illegal.
Powerline blog has an excellent analysis on the legality of the President's actions. Long - but definitive and worth the time. He's on strong legal ground - both in law, precedent and history!
