Bin Laden's Al Qaeda ("The Base") network is expanding. It's now believed to include about two dozen terrorist organizations in 50 countries, including the United States. But the leaders and the camps have to be somewhere, and we know the countries that have allowed the greatest number of such camps on their soil: Afghanistan, Iran, Iraq, Libya, the Sudan and Syria.

Ultimately, the only way to stop further terrorist attacks is to show that we will attack governments that support terrorism as well as the terrorists themselves.

This is really, really important. This is why we have to attack the governments that sponsor terrorism as well as the individuals who actually planned the attacks on the World Trade Center and the Pentagon.

And here is why we must do it without delay: terrorist attacks are becoming more frequent and more destructive. A suitcase of explosives downed Pan Am Flight 103 over Lockerbie, Scotland, in 1988. Truck bombs mangled the WTC in 1993 and the Khobar Towers, in Saudi Arabia, in 1996. Nearly simultaneous truck bombs destroyed the American embassies in Kenya and Tanzania in 1998. The September 11 attacks used four fully fueled passenger planes as flying bombs.

Left unchecked, matters will get worse. As early as the 1990s, bin Laden's agents tried to buy chemical weapons and material for nuclear bombs. It is only a matter of time before they finally get them. We must, at all costs, wipe out the terrorists before that happens.
