Somebody forgot to tighten the verb?

Aside from Baddest Photoshop of the (still-young) Year, we have a genuine grammar question here. Is Iran rattling because somebody left the transitizer loose on the verb and the direct object is about to fall off, or are "Iran rattles" something the newly inaugurated 3-year-old bangs on his crib when he needs attention?

If you had to pick someone who was rattling some swordlike object in this scenario, would it be the one who said "this is not the first time that an inexperienced person has threatened Iran," or the one who said ... how did that go again?

Trump tweeted, "Iran has been formally PUT ON NOTICE for firing a ballistic missile. Should have been thankful for the terrible deal the U.S. made with them!"

He added in another tweet: "Iran was on its last legs and ready to collapse until the U.S. came along and gave it a life-line in the form of the Iran Deal: $150 billion."

You'd like to think that eventually even the droolers will realize that when Iran is being the adult in the room, their side has cause for concern. Maybe someone at the Park Service could say something distracting and get his attention again?
