That's what Trump told you to sound badass and edgy. His advisors might have a more complicated rationale that's harder to explain to the public than a single 3-letter word.
Foreign policy of the US has always been about orchestrating coups to create passive client states for US capitalists more efficiently extract natural resources, going back to 1953 in Iran. Only difference with Trump is he has done away with pretenses. He says the quiet part out loud. He says things like "we want the minerals in Ukraine", and then negotiates a mineral deal. He talks about conquering Panama, Greenland, Canada. He is an unabashed imperialist. It's been at least 70 years of this happening, catch up already. And it goes back even further, to the US controlling the Philippines in 1898, and the Monroe Doctrine in 1823.
