Saudis to build fence; Why can't USA?

The sensible Saudis are planning to emulate the Israelis and build a wall separating their Kingdom from terrorist-ridden Iraq next door.

Why can't the US do the same on our fractious borderline with Mexico, where druglords and terrorists infiltrate along with thousands of illegal workers? The US does not have the political will, no..... courage to defend itself that more sensible and less leftist countries like Israel and Saudi Arabia can muster.

Remember the terrorist stopped at the Canada/Washington border crossing who was going to blow up LAX to welcome in the New Millenium? Our memories are so short in the US that we are setting ourselves up for another massive attack, somewhere, someday.
