Donald Trump has been engaged in a war of words with Jeb Bush after he suggested that Bush’s older brother and former President George W. Bush didn't keep the country safe because 9/11 occurred on his watch.

The younger Bush has defended his brother by saying that no one could have seen the terror attack coming, also criticizing Trump's "lack of understanding" regarding foreign policy.

On "Hannity," however, Donald Trump pointed out that in 2000, 19 months before September 11, 2001, he wrote extensively about the terrorism threat facing the U.S. in his book "The America We Deserve."

"I really am convinced we’re in danger of the sort of terrorist attacks that will make the bombing of the Trade Center look like kids playing with firecrackers," Trump wrote. "No sensible analyst rejects this possibility, and plenty of them, like me, are not wondering if but when it will happen."

Trump even identified Al Qaeda leader Usama bin Laden by name.

"One day we’re told that a shadowy figure with no fixed address named [Usama] bin-Laden is public enemy number one, and U.S. jetfighters lay waste to his camp in Afghanistan," he wrote. "He escapes back under some rock, and a few news cycles later it’s on to a new enemy and new crisis."

Trump told Sean Hannity that he believes that as president, he could have prevented 9/11 because he has extremely tough illegal immigration policies, which would have kept some of the 9/11 hijackers out of the U.S.
