David Headley liked Osama's theory on women!

New Delhi: Pakistani-American terrorist David Coleman Headley liked Osama bin Laden's theory of having several women in one's life but found Pakistani women to be cumbersome than those from Arab countries, says a new book.

Laden's father, Mohammed bin Laden, had at least 54 children from 22 different wives. So while Laden was attending college, he and a friend decided they would each also take several wives and have large families.

Laden himself had over 20 children from six wives.

"Laden later developed a theory on the advantages of having several women in one's life. Four was the optimal number, prescribed by the Prophet Muhammad himself, according to bin Laden," writes investigative journalist Kaare Sorensen in his new book "The Mind of a Terrorist."

"One is okay, like walking. Two is like riding a bicycle: it's fast but a little unstable. Three is a tricycle, stable but slow. And when we come to four, ah! This is the ideal. Now you can pass everyone!" he says quoting Laden.

According to the author, Headley was, as usual, very excited about Laden's thoughts, including those on women.

"Headley himself loved women. And he had many of them. He bragged to a group of friends that he had been with more black women than his entire class at the military academy combined. That was about one hundred students," the book, published by Penguin Random House India, says.

It contains Headley's personal emails, revealing the psyche of the terrorist.

"But he (Headley) found Pakistani women to be cumbersome. They'd all seen too many Bollywood movies with big, dramatic romance scenes, and they didn't want to live their lives as the third or fourth wife in a complicated marriage," argues Sorensen.

"Arab women are much more understanding and open to it. They only ask that you be fair," Headley wrote to his friends, he says.
