If the US had true gumption, they would be testing their hypersonic missiles via launches out of Ukraine aimed at high value russian military targets, with a pretend excuse that it was actually Ukraine launching the missile.

I can guarantee you most of Ukraine would support this (I live in Ukraine) and the “red line” bla bla is just westerners falling prey to russian foreign propaganda initiatives.

The US is behind in this tech because we didn’t think we needed it. I wonder what changed the Pentagon’s mind? Perhaps they’ve been impressed by what Russia has done in Ukraine.
