Seventeen years after the start of the first major U.S. war on terrorism – and tens of thousands of casualties and more than two trillion dollars later – the U.S. still lacks a credible database on international terrorism. There is no common official database at the interagency level, there are deep disagreements over the size and success of given threats, and there are major gaps in coverage. Each “war” on terrorism has its own approach (and usually approaches) to estimating the threat and to judging what parameters are important. There are a wide range of databases outside the U.S. government, ranging from commercial efforts to academic and NGO assessments. They often sharply disagree, and many are clearly political or ideological in character. The closest thing to an official database is the one used by the U.S. State Department in its Country Reports on Terrorism and its Annex of Statistical Information. The report and annex provide an overview of the global trends in terrorism.
