Criticizing Obama's decision to send more troops to the Afghanistan, the son of the al Qaeda leader said, "If I was in his position, the first thing I would do is make a truce. Then for six months or one year, no fighting, no soldiers. Afghanistan can never be won. It has nothing to do with my father. It is the Afghan people."
In the past Omar, who says he is one of the 11 sons of bin Laden, painted a picture of his childhood in jihadist camps, where fighters tested chemical weapons on puppies.
In the interview, which will be published in the Friday, Jan 22 issue, Omar goes on to say that his father was overwhelmed with joy when George W Bush won the elections in 2000.
Osama apparently predicted that Bush was just the kind of president the United States needed - "one who will attack and spend money and break the country."
US is lucky that it has not found and killed his father, Omar reportedly told the magazine, warning, "It is going to be worse when my father dies. The world is going to be very, very nasty then. It is going to be a disaster," bin Laden is quoted as saying.
The magazine reports that Omar, who was making a living as a scrap metal merchant in the Saudi, compared himself to Hollywood star Mel Gibson and dreamed of working for the United Nations and meeting Obama and US secretary of state Hillary Clinton.
