Terrorists are not suspended in mid-air. It takes the active support of states to provide the cover an organization like Al-Qaeda needs. That is why Saddam needs to be taken out. The WMD is important, and I'm not discounting it... but he is working through and with Al Qaeda... and other organizations.
Hezzbollah doesn't work independent of Islamic Jihad. Nor does Hamas work independent of Al Qaeda. These organizations get political and financial support from Iraq, Iran, Syria, Saudi Arabia.
Just follow the trail of the Iranian revolution. See how those groups worked together for the otherthrow of the Shah. See, how Iran works now through Hezzbollah, Islamic Jihad.
What the media wants to do is just separate the entities from each other. If we allow that to happen... then terrorism cannot be defeated. Because Hamas will just absorb the men, supplies, sources of Al Qaeda.
Al Qaeda is one head of a multi-headed snake.
