The US President had said on Monday that if Iran strikes, US forces will strike back "perhaps in a disproportionate manner" as tensions escalated between Iran and the US.
Trump added that the US has spent "two trillion dollars" on military equipment and if Iran attacks an American base then "we will be sending some of that brand new beautiful equipment their way, without hesitation".
Meanwhile, Iran's head of Iran's Revolutionary Guards Hossein Salami told mourners in Soleimani's hometown of Kerman that the country will take revenge "hard and definitive revenge" as thousands gathered at Soleimani funeral procession.
On Tuesday, defence secretary Mark Esper dismissed reports which indicated that US troops would be pulling out of Iraq.
In a leaked letter, bearing the name of US General William Seely, said that "CJTF-OIR will be repositioning forces over the course of the coming days and weeks to prepare for onward movement," adding, "We respect your sovereign decision to order our departure."
Pentagon Joint Chiefs Chairman Mark Milley was, however, quick to add that the letter was just a "draft" which was "poorly worded". Milley called it an "honest mistake".
"This was a mistake," Milley said. "It shouldn't have been sent."
