Three things we know. One, Russia always breaks treaties. Two, development of the land-based cruise missile was ongoing for several years. Three, last year's test of the missile was a flop. Maybe it was fixed, but we know that Russian armaments like their nuke submarines are more a danger to themselves than to us. Russia is a third rate power, well behind the US and China. They could never win a war; they are only capable of bullying defenseless neighbours. If uncle vlad wants to renew the arms race, then he will have it. trumpty-dumpty has already promised to rebuild the US military and has a strong economy to back it, unlike uncle vlad whose economy is in reverse gear. Keep and strengthen the sanctions and arm eastern Europe. Russia will be Soviet Union 2.0 in no time.
