"We will not stop at Kyiv, Warsaw, Paris. We will stop when we feel secure."
What is security for Russia? The destruction of NATO?
Russia has been living in "counteraction and struggle" with external "bad enemies" for a very long time. This is how the Russian government consolidates society and explains all the problems to it.
AGM-158 JASSM's with CHAMP packages. Stealth cruise missiles with anti-electronics packages. Would bring down the bloodshed significantly while disabling enemy communications, launchers, radar installations, etc. These can be fired by F-16s.
The CHAMP is superior to other electronic warfare weapons because it destroys electronics, rather than jamming which temporarily affects systems that come back online when it stops being applied....
CHAMP is capable of up to 100 shots per sortie.
You gotta imagine the US has at least one or two publicly unknown weapon types socked away for a rainy day. At the outside, perhaps something crazy in the vein of Rods from God.
