Should the west be afraid of something Putin might do?

The West and the rest of the world should be afraid of something Putin might do. He has shown that Russia has the capability to take out satellite's. Russia claims they have super fast ballistic missals that are impossible to hit with another missal. And it is possible that Russia has hacked into US and its allies defence computers. Russia's war in the Ukraine isn't going well so to save face he just might just start launching nukes. Cheers and happy weekend!
