Full paragraph before it chopping a part out and taking it out of context:

"Before September the 11th, many in the world believed that Saddam Hussein could be contained. But chemical agents, lethal viruses and shadowy terrorist networks are not easily contained. Imagine those 19 hijackers with other weapons and other plans -- this time armed by Saddam Hussein. It would take one vial, one canister, one crate slipped into this country to bring a day of horror like none we have ever known. We will do everything in our power to make sure that that day never comes."

Now where did it say that Saddam had a connection with 9/11?

It does not say. It does not imply that. It merely rasies the future specter of terrorists with chemical or bio weapons that Saddam was belived, as far back as 1998 before, GWB could have "cooked" the evidence, to have possessed. And it states thet the events of 9/11 made more people aware of the possibility of such things happening.

Is it not the responsibility of the government to consider future threats to security and possibly avoid them like an asteroid hit?

If you really believe what you are talking about, you will answer these two questions directly. oTHERWISE YOU WILL HAVE TO DO A LITTLE DANCE AND ATTEMOPT TO DISCREDIT ME FOR ASKING THE QUESTIONS
