If Russia should win ... and I hope they don’t ... they must not ... then there will be many more wars like that in the future.
If they throw out their nuclear blackmail and the world yields then there is no other way than to yield every time. The alternative is to tell them to go stuff it every time, because once you yield to nuclear blackmail then keeping the same you’ll yield every time.
The Russians are almost certainly in the process of upgrading their weapons.
Expect them to get weapons as good as the US has, but as many as their weapons factories can make.
