President Donald Trump on Monday said he’s expecting more American service members to be killed in the ongoing aerial campaign against Iran for as long as U.S. forces can “finish the job.”

Asked how many deaths on the U.S. side would be acceptable to him after Pentagon officials announced that a seventh American service member had been killed in the conflict, Trump told reporters at a press conference in Doral, Florida: “When you have conflicts like this, you always have death.”

Trump’s latest comments came just hours after he claimed the joint U.S.-Israeli bombing campaign against Iran could wrap sooner than expected as global markets have continued to tumble from the effects of rising oil prices as a result of the week-old war.

In a Monday interview, Trump told CBS News he thought the war is “very complete, pretty much.”

“They have no navy, no communications, they’ve got no Air Force,” he said.

Trump also told the television network that the U.S. war effort is now “very far” ahead of the four to five week timeline he and his advisers had estimated when the air campaign began just over one week earlier.
