I agree with your sentiment. There are videos that appear to depict the main explosion resulting from a missile strike, the folk filming react to it as it enters the frame immediately prior to detonation.
It's wrong to classify something false with certainty when it is just conjecture and likely of a political nature at that.
Trump’s statements on the matter are of no interest though. If it was possibly going to lead to some imminent executive action, then it might be. It all depends. For most topics, his statements are not worthy of posting here imho.
That Trump's statement is false and dangerously irresponsible is not OP's fault.
