It is not a troop deployment, but an expanded repositioning

Trump will likely engage in massive propaganda, saying, 'The elite fleet from South Korea, the world's 6th strongest military, will be deployed for the United States.'
Iran's stance will likely be different,
but it seems this administration inherited the previous administration's characteristic of lacking 'honesty.'
Anyway, I'm rooting for you, Mr. President. Nice job.
You sure do take a lot of people out for golf rounds.
