You're dumb. The distinction, and it's incredibly important, is that hypersonic missiles do it within the atmosphere and not in the total lack of or extremely very little atmosphere that ICBMs travel at. Additionally they don't travel thousands of miles, they travel shorter distance and likely to a moving target.
What you're saying is like me saying it's not impressive that a bugatti, a street legal car can reach 300mph because dragsters have been for many many years.
They've been redefining things. China's hypersonic missile are in fact ICBMs. While they do so at lower altitudes they have a distinct vertical boost phase. These are ballistic missiles. Basically next gen mirvs. These are not what everyone thinks of for hypersonic missile.
The real and traditional technology does have a boost phase but it is largely horizontal. It's speed comes from advanced engine and aerodynamic technology. (((MSM))) has purposely blurred the lines so as to bolster their FUD in efforts to promote the MIC and pointless wars like Ukraine.
While effective with nukes (which is china's anti ship hypersonic tech - really a mirvs), they are simply improved next gen versions of icbm mirvs. These are not in the actual class of hypersonic technology as sold to the west. Mirvs have always been hypersonic, albeit with limited control. Thus the need for decoys.
German V-2 rockets were fucking hypersonic. It's meaningless propaganda they are using to justify defense spending and to keep the stupid people supporting their war.
