This statement presumes that war is a temporary thing as it has been in the past. And after that war is over, constitutional rights suspended for the duration of that war will be restored in full, correct?
My question to you is: What theoretical conditions must be met in order for the War on Terrorism to be declared over?
I submit that because the WoT is not a traditional style war, and by definition is a war against a method and not a tangible object such as a country(s), person(s), or army(s), it cannot be won. Even the president has stated the war will last several decades. And after a generation, restoring constitutional protections will be as unrealistic as repealing the income tax.
Because of this, WoT exceptions to the constitution are far more damaging to our rights than traditional wars. They must be considered in an entirely different way.
