We still have a long and difficult struggle before us. Intelligence regarding terrorist groups is often difficult to obtain becasue of the tight-knit nature of these organizations. Captured terrorists willing to talk after an attack are often low-level operatives who don't know much about the inner workings of their organization. Even if we learn about the terrorist leaders, we may not know where they are located at any given time. Nonetheless, we have already made progress regarding international cooperation, hijacking prevention, and embassy security.
Terrorism is ultimately the weapon of the weak, the cowardly, and the marginal.
I am confident that we can prevail through a sustained effort of will and ingenuity.
