Saddam Hussein and Muammar Gaddafi were the rulers of Iraq and Libya respectively.
While talking in the CNN's talk show "State of the Union" the billionaire real estate tycoon also said that Middle East "blew up" around US President Barack Obama and former secretary of state Hillary Clinton, his biggest Democratic rival in the race for the White House.
"100 per cent," Trump said when asked if the world would be better off with Hussein and Gaddafi still at the helm in Iraq and Libya.
Atrocities were carried out by both the dictators in their respective countries, but, according to Trump the situation was far better than the present situation in Iraq and Libya.
"I mean, look what happened. Libya is a catastrophe. Libya is a disaster. Iraq is a disaster. Syria is a disaster. The whole Middle East. It all blew up around Hillary Clinton and around Obama. It blew up," said Trump.
He termed Iraq as "Harvard of terrorism".
Calling Iraq the "Harvard of terrorism," Trump said the country had turned into a "training ground for terrorists."
"If you look at Iraq from years ago, I'm not saying he (Saddam) was a nice guy. He was a horrible guy but it's better than it is now," Trump said.
