Gawd, if only we had elected Rudy Giuliani president. Just think -- as he did last night with Sean Hannity:

Giuliani: The reality is, we just need the political will to do it. It's a 2,000-mile border. It isn't that big. If you took about 20,000 border patrol agents and you put them in substations about every fifty miles, you'd be able to cover the border -- maybe even every twenty-five miles -- and then you'd use photographic equipment, nighttime photography, heat-seeking equipment, motion-detection equipment. You'd alert the people at the stations, they'd go there and stop people from coming in.

Hannity: It's that easy! It really is, that, it's --

Giuliani: It's a matter of political will. When I was running for president, I said that it would be easier to control illegal immigration than it was to reduce homicide in New York by fifty percent.

Of course, Giuliani doesn't explain how he would deal with the over 40 percent of illegal immigrants who crossed the border legally and overstayed their visas.

Nor does he contemplate the costs of running that kind of border security every twenty-five miles -- with simply no guarantee it will actually work. Indeed, every scheme they've ever devised has failed, because people always figure out ways around them. Didn't we just blow $2 billion on a "virtual fence" that turned out to be a "real world failure"?

But those are niggliing details, no doubt, too insignificant for real "terrorism experts" like Rudy Giuliani.
