The US admninistration is not looking for this law change to enable them to "Better fight the War On Terror". The truth is that the US Administration need the law relaxed because they think that it will then make it easier for them to get a retrospective law change that may further help them to crawl out of a rather deep set of legal and constitutional holes that they currently find themselves in. You see, the Dubya administration has trampled all over the laws of the US and the Constitution itself and they have, as seen in the video, admitted it along the way. The problems they now face are coming from all directions such as the Electronic Frontier Foundation's successful application to sue AT&T for handing over phone records without a warrant.
The President has already blocked one investigation
into his conduct regarding this issue and now they are looking to srike down all others before they even get started.
