Guiliani questions Obama's nuclear strategy shift

Some leading experts have questioned President Obama's recent announcement that the American nuclear strategy would be narrowed and that attacks with biological or chemical weapons would not be met with a nuclear reprisal.

"I don't know if they have any idea of how catastrophic a chemical or biological attack on the United States can be," Rudy Giuliani told Sean Hannity on Hannity's television show this week.

Giuliani told Hannity that, in the wake of the September 11, 2001 terror attacks, he convened a panel of experts and doctors to discuss potential biological warfare threats and how to deal with chemical warfare.

"A few weeks later we were hit with anthrax," Giuliani said. "The meeting lasted about two-and-a-half, three hours. I left there, and I couldn't sleep that night. I couldn't sleep many nights then. Couldn't sleep that night because there were a couple of things they could have done to us that our best answer would have been to put people on Randall's Island and just let them die."

Giuliani called President Obama's decision to remove the chances of nuclear reprisal "entirely irresponsible an really naive," saying that thousands and thousands of people could be killed by biological agents or chemical weapons.

"I can't imagine why a president of the United States would want to tie our hands and how, first of all, we deter and, number two, how we respond to catastrophic attack," Giuliani said.
