after ordering the drone strike which killed Iran's General Qasem Soleimani.
Trump said that Soleimani was "actively planning new attacks" against the US in Baghdad and beyond, deriding his Democratic opponents.
"We stopped him, and we stopped him quickly and we stopped him cold," Trump added, in the wake of opposition to the escalating tensions with Iran.
Iran's Soleimani spearheaded Iran's military operations in the Middle East as head of the country's elite Quds Force.
He joined the Revolutionary Guards - who have been declared a foreign terrorist organisation by the US - in 1979, taking over as head of the Quds Force in 1998.
He was considered to be one of the most powerful figures in the country, masterminding Iranian intelligence and military operations abroad.
Outside of war-games he was considered to be even more pivotal, with commentators comparing his role to that of US Vice President, Mike Pence.
He is thought to have directly reported to Ali Khamenei, Iran's Supreme Leader.
He gained a mysterious reputation, and was reported to have survived many assassination attempts.
Israel, the US and Saudi Arabia were closely following his movements as he cultivated Iran's military influence in the Middle East, with the US believing he was behind attacks on Americans staying in the region.
