"As president, my priority is to end conflicts, not start them, but I will never hesitate to wield American power if it's necessary to defend the United States of America or our partners," Trump said.

鈥淥ur soldiers are fighting against the enemies of civilization and defeating terrorism. Our soldiers embody American power and are the strongest in the world,鈥� he added.

鈥淨atar will invest $10 billion in Al Udeid Air Base and the US base will soon have the F47 fighter jet,鈥� he explained.

鈥淲e will not hesitate to use force to defend America and our allies,鈥� he said.
