Logic 201 - Specious Reasoning

This is an excellent column by Arianna Huffington about the Bush administration's mastery of logic-defying reasoning.

She incorrectly identifies, however, the following logical fallacy:
But the White House continues to razzle-dazzle the Beltway with its command of the Undistributed Middle: The president invaded Iraq. There have been no terrorist attacks in America since 9/11. Therefore, the invasion of Iraq has made us safer--and lit the torch of freedom throughout the Arab world.

This would be more appropriately labeled as specious reasoning, and we'll let Lisa Simpson explain this:

Homer: Not a bear in sight. The Bear Patrol must be working like a charm!
Lisa: That's specious reasoning, Dad.
Homer: Thank you, dear.
Lisa: By your logic I could claim that this rock keeps tigers away.
Homer: Oh, how does it work?
Lisa: It doesn't work.
Homer: Uh-huh.
Lisa: It's just a stupid rock.
Homer: Uh-huh.
Lisa: But I don't see any tigers around, do you?
[Homer thinks of this, then pulls out some money]
Homer: Lisa, I want to buy your rock.
