"Since the September 11 attacks and the defeat of the Taliban, al Qaeda's funding has decreased significantly. The arrests or deaths of several important financial facilitators have decreased the amount of money al Qaeda has raised and increased the costs and difficulty of raising and moving that money.
"Some entirely corrupt charities are now out of business, with many of their principals killed or captured, although some charities may still be providing support to al Qaeda.
"Moreover, it appears that the al Qaeda attacks within Saudi Arabia in May and November 2003 have reduced - perhaps drastically - at Qaeda's ability to raise funds from Saudi sources. Both an increase in Saudi enforcement and a more negative perception of al Qaeda by potential donors have cut its income."
This is not to suggest that the war on terror is anywhere close to being won, but it does suggest that things are certainly moving in the right direction.
