US has allies on the other size of the strait of hormuz (oil selling nations and other relations) and (UN/US owns Iraq).
US has every right to shipping lanes AND security surveillance of the shipping lanes
US can and should have military vessels (not necessarily an armada) in any shipping areas it has ships in to "deter piracy" and also bullies from stealing US ships - which is absolutely an issue, as the international law is that all trade ships are "un-protected" and piracy certainly does occur regularly
