Here's a NASA conference paper from 2001 on hypersonics[0]. So it's not that it hasn't been worked on, it's just that it never delivered any tangible results. Why? They spent trillions on planes and aircraft carriers that didn't really produce the expected results in modern warfare. Why is the moneyhose still feeding into that? The question of morality is REALLY off-topic and always comes up when someone makes a point about the inefficiencies of certain systems, instead of actually addressing the main concern, which is why isn't the money being spent efficiently? And where are the checks to make sure it is? But the only country that has so far used nuclear weapons and littered the planet with depleted uranium wasn't the Soviet Union was it? That country also threatened to use them in Vietnam[3] and brought the biggest nuclear weapon on its carrier to threaten India in 1971[1]. It also wasn't Russia that unilaterally pulled out of the arms agreements. Bolton just argued that Russia was violating it anyway, so there's no point keeping it[2]. Look, I'm not trying to bash that country, but hold your horses when talking about morals, in a discussion that is ultimately a game of power between superpowers. The reason why the US should stay a superpower isn't because it's so morally superior, it's because, if there isn't some sort equilibrium of power, one side is bound to become a bully. Just like how in a democracy there is an intention to have an equal separation of power which for the last decades has been gradually eroding, giving the executive ever more power, leading to all sorts of problems for society.
