Everyone has interest in that strait, and that's what he's always counting on in every context - people acting in own self interests, cos that's the law of nature and sign of sovereign Nations, which is the new order.
The economic strain is like tariffs: pressure. How long will countries endure when they know what will fix it? Saudi Arabia is willing, but not before a coalition of self interests is set up. If UK joined, it would surrender its supremacy, cos Mid East instability is its game. This will destroy the globalist strangle completely. A crucial moment.
Plus, he never said U.S would run the strait on its own, cos that would DEFINITELY be something he'd mention, with pride even had that been the case. This will become the economic gathering point of the world, instead of just the UK.
