Reagan didn’t create pointless wars
...and also, the USSR ended 3 decades ago.
Maybe Putin wants The Russian Empire again, and not the USSR.
He wants to try as best he can restore the borders of Czarist Russia (several 100 years in the making!) - 1914 borders.
I think regaining Poland & Finland is not going to happen. Possibly gain the Baltic nations unless the figure out how to align themselves strongly with other Baltic powers like Poland, Finland, Sweden and others.
I still think NATO is obsolete. Its time for it to go, replace it with three European alliances - Atlantic, Baltic & Central Europe. We can be member in Atlantic and friendly observer in the others.
