When I left the Bush administration in 2003, it was clear to me that its strategy for defeating terrorism was leaving our nation more vulnerable and our people in a perilous place. Not only did its policies misappropriate resources, weaken the moral standing of America, and threaten long-standing legal and constitutional provisions, but the president also employed misleading and reckless rhetoric to perpetuate his agenda.

This week's State of the Union proved nothing has changed.

Besides overstating successes in Afghanistan, painting a rosy future for Iraq, and touting unfinished domestic objectives, he again used his favorite tactic - fear - as a tool to scare Congress and the American people. On one issue in particular - FISA (Foreign Intelligence Surveillance Act) - the president misconstrued the truth and manipulated the facts.

Let me be clear: Our ability to track and monitor terrorists overseas would not cease should the Protect America Act expire. If this were true, the president would not threaten to terminate any temporary extension with his veto pen. All surveillance currently occurring would continue even after legislative provisions lapsed because authorizations issued under the act are in effect up to a full year.

Simply put, it was wrong for the president to suggest that warrants issued in compliance with FISA would suddenly evaporate with congressional inaction. Instead - even though Congress extended the Protect America Act by two weeks - he is using the existence of the sunset provision to cast his political opponents in a negative light.

For this president, fear is an easier political tactic than compromise. With FISA, he is attempting to rattle Congress into hastily expanding his own executive powers at the expense of civil liberties and constitutional protections.

I spent most of my career in government fighting to protect this country in order to defend these very rights. And I know every member of Congress - whether Democrat or Republican - holds public office in the same pursuit.

That is why in 2001, I presented this president with a comprehensive analysis regarding the threat from al-Qaeda. It was obvious to me then - and remains a fateful reality now - that this enemy sought to attack our country. Then, the president ignored the warnings and played down the threats. Ironically, it is the fear from these extremely real threats that the president today uses as a wedge in a vast and partisan political game. This is - and has been - a very reckless way to pursue the very ominous dangers our country faces. And once again, during the current debate over FISA, he continues to place political objectives above the practical steps needed to defeat this threat.

In these still treacherous times, we can't afford to have a president who leads by manipulating emotions with fear, flaunting the law, or abusing the very inalienable rights endowed to us by the Constitution. Though 9/11 changed the prism through which we view surveillance and intelligence, it did not in any way change the effectiveness of FISA to allow us to track and monitor our enemies. FISA has and still works as the most valuable mechanism for monitoring our enemies.

In order to defeat the violent Islamist extremists who do not believe in human rights, we need not give up the civil liberties, constitutional rights and protections that generations of Americans fought to achieve. We do not need to create Big Brother. With the administration's attempts to erode FISA's legal standing as the exclusive means by which our government can conduct electronic surveillance of U.S. persons on U.S. soil, this is unfortunately the path the president is taking us down.

So it is no surprise that in one of Bush's last acts of relevance, he once again played the fear card. While he has failed in spreading democracy, stemming global terrorism, and leaving the country better off than when he took power, he did achieve one thing: successfully perpetuating fear for political gain.

Sadly, it may be one of the only achievements of his presidency.
