Why? US foreign policy hasn’t changed since manifest destiny so threats to attack are literally nothing new, it’s still ““aiding”” a lot of western countries with stationed soldiers in case some countries outside the western bloc decides to attack, nuclear tests is a bit more iffy after the cold war, but can easily be justified by wars breaking out…

There’s genuinely no reason to cut ties with US for any country, doing so would just shoot it in the foot since you lose one of the largest economies for trade.
