Not much to do except shake the head and wonder at the world…

WASHINGTON (CNN) — Colorado Rep. Tom Tancredo’s campaign stood by his assertion that bombing holy Muslim sites would serve as a good “deterrent” to prevent Islamic fundamentalists from attacking the United States, his spokeswoman said Friday.

“This shows that we mean business,” said Bay Buchanan, a senior Tancredo adviser. “There’s no more effective deterrent than that. But he is open-minded and willing to embrace other options. This is just a means to deter them from attacking us.”

On Tuesday, Tancredo warned a group of Iowans that another terrorist attack would “cause a worldwide economic collapse.” IowaPolitics.com recorded his comments.

“If it is up to me, we are going to explain that an attack on this homeland of that nature would be followed by an attack on the holy sites in Mecca and Medina,” Tancredo said. “That is the only thing I can think of that might deter somebody from doing what they would otherwise do. If I am wrong, fine, tell me, and I would be happy to do something else. But you had better find a deterrent, or you will find an attack.”

Tom Casey, a deputy spokesman for the State Department, told CNN’s Elise Labott that the congressman’s comments were “reprehensible” and “absolutely crazy.” Tancredo was widely criticized in 2005 for making a similar suggestion.
