A PRE-9/11 WORLD

President Bush on Monday delivered an anticipated speech on immigration. During the primetime address he acknowledged:

[T]he United States must secure its borders. This is a basic responsibility of a sovereign nation. It is also an urgent requirement of our national security ... we do not yet have full control of the border, and I am determined to change that.

Our national security depends on secure borders. Bush said terrorists could sneak across the U.S.-Mexico border. Given that backdrop, it was amazing that Bush didn't make a single reference to the attacks of Sept. 11, 2001. Why not?
