You are underestimating how vast Russia (and Ukraine) are.

Moscow is out of reach even for the longest range (300km) HIMARS missiles which are not supplied to the Ukraine.

GPS jamming protects Russia's command and control structures from American intermediate range cruise missiles that can be launched from Mk41 launchers in Romania and Poland as well as from American ships.

I don't think Mk41 are operating in these two countries.[0] They do have Aegis Ashore [1] though which is an anti-ballistic defense system. AA uses SM-3 missiles that in theory could reach Moscow though.

Aegis uses Mk-41, which is a unified launcher for SM-3 and Tomahawk missiles. I believe Aegis Ashore uses the same launcher.

Albeit ineffectively, because they have an INS backup.

Also terrain contour matching [0] and Digital Scene Matching Area Correlation [1].

GPS spoofing will not prevent a US attack on Russia, it may prevent angry Russians from finding Putins' office, though.

What does GPS have to do with finding Putin's office?
