...
I am especially troubled by these shifting justifications because I and most Americans strongly support the President on the use of force in response to the attacks on September 11, 2001. I voted for Senate Joint Resolution 23, the use of force resolution, to go after al Qaeda and the Taliban and those associated with the tragedies of September 11. And I strongly support military actions pursuant to Senate Joint Resolution 23.
But the relentless attempt to link 9-11 and the issue of Iraq has been disappointing to me for months, culminating in the President's singularly unpersuasive attempt in Cincinnati to interweave 9-11 and Iraq, to make the American people believe that there are no important differences between the perpetrators of 9-11 and Iraq.
Mr. President, I believe it is dangerous for the world, and especially dangerous for us, to take the tragedy of 9-11 and the word "terrorism" and all their powerful emotion and then too easily apply them to many other situations -- situations that surely need our serious attention but are not necessarily, Mr. President, the same as individuals and organizations who have shown a willingness to fly planes into the World Trade Center and into the Pentagon.
Let me say that the President is right that we've got to view the world, the threats and our own national security in a very different light since 9-11. There are shocking new threats. But, Mr. President, it is not helpful to use virtually any strand or extreme rhetoric to suggest that the new threat is the same as other preexisting threats. Mr. President, I think common sense tells us they are not the same and they cannot so easily be lumped together as the President sought to do in Cincinnati.
Mr. President, I've reviewed the intermittent efforts to suggest a connection of 9-11 and Saddam Hussein or suggest the possibility that such a connection has developed since 9-11. Let me be very clear. If in fact there was a connection in planning together for the 9-11 attack by Saddam Hussein or his agents and the perpetrators of 9-11 and al Qaeda, I've already voted for military action. I have no objection.
But if it is not, if this is premised on some case that has supposedly been made with regard to a subsequent coalition between al Qaeda and the Iraqi government, I think the President has got to do better. He's got to do better than the shoddy piecing together of flimsy evidence that contradicts the very briefings we've received by various agencies, Mr. President.
...
My constituents have voiced their concerns in calls, at town meetings, in letters and through e-mail or with faxes. They aren't calling for Congress to bury our heads in the sand. They are not naively suggesting that Saddam Hussein is somehow misunderstood. But they are asking questions that bear directly on our national security, and they are looking for answers, Mr. President, that make sense. They are setting the standard, Mr. President, just as they should do in a great democracy. Their standard is high. We should work together to develop a policy toward Iraq that meets it. I am proudly one of his constituents with high standards.
