This is interesting thinking as well. Defending this stuff kind of stuff is really unfortunate.
In this memoranda, for example, from Yoo on 9/25/01 (warning large pdf file) it states warrantless searches can be Constitutional "when special needs, beyond the normal need for law enforcement, make the warrant and probable cause requirement impracticable." Yoo goes on to make the case, when the President does it, it isn't illegal. It's absolutely foolish to think these guys weren't just setting up cover for planned mass surveillance that they then carried out.
FISA warrants were easy to come by. Bush wanted to record literally every phone call both within and without the US, that was supposedly the impractical to get a warrant circumstance. Well, d'uh. Just what probable cause was there for wiretapping everyone?
Did Congress agree? No.

You really need to stop making things up:

The Foreign Intelligence Surveillance Court of review has ruled that the government's right to intercept emails and wire-tap international phone calls without a warrant is legal and constitutional.
This a huge victory for the Bush Administration who faced extreme criticism while wire tapping international phone calls without warrants saying they had the right to do so for national security reasons.
Dean Boyd, the Jusice department spokesman says "The Department of Justice is pleased with this important ruling." The Court said that the Protect America Act of 2007 was reasonable under the fourth Amendment, The court rarely releases their rulings.
