Something called Control Risk Groups out of London has completed a study that has found we're safer now than at any point since 9/11:

Although the headlines in 2005 will continue to be dominated by the ongoing 'War on Terror', the report argues that successful action against al-Qaida's leaders, tightening of anti-terror financing laws and the continuing restructuring of intelligence and law enforcement agencies have made the United States safer than at any point since 9/11.

The organized matrix of international terrorism has been shattered and replaced by a new paradigm that sees small, decentralized cells of local militants attacking Western interests abroad.

The study foresees continued security problems in Iraq (where there's, well, a war against terrorists going on) and believes Iran's nuclear program will continue to be an issue. But as far as the U.S. homeland, it paints a reassuring picture. (As it probably should.)

Does anyone still get agita in tall buildings, though? On airplanes? Driving through tunnels? The answer: Probably yes, and probably for a good long while, too, though less over time.
