singapore is a fucking city state that could be blockaded by a single us destroyer you are a fucking moron. the instant war breaks out we would have control of the straits of malacca and there's fuck all china could do about it. you'd also see every country that has had their territorial waters fucked by china (vietnam, phillipines, basically every fucking country in the region) supporting the us. singapore would also not resist us influence over china's especially when they have no means of actually doing anything about it.
