This just shows how the US lied about Russia breaking the INF Treaty limitations. The US themselves wanted to break the treaty, so they accused the Russians of doing it as a cover to put this infringing system into place. And the gullible Europeans are just too dumb to realize it. They just put themselves into the crosshairs of future Russian retaliation. As well Japan, South Korea and the Philippines in Asia will put themselves into the crosshairs of China in case these systems are to be deployed there.
Putting these systems into service basically lowers the nuclear threshold.
As soon as Iran North Korea and much more significantly China started developing their own systems the INF treaty was dead. There would be no way the US would constrain itself where China was able to develop and deploy their own systems. But yes they used the pretext of Russian violations to justify their abjuration to the treaty.
