Russia should attack Ukraine because .... 1654?
Right.
History should move backwards to whatever past circumstance YOU want.
Let’s ignore that aberration called present reality.
No, what I am saying, slow one, is that there are 337 reasons/years for Russia to want to take back the Ukraine in response to NATO aggression and its ceaseless march eastwards towards Moscow. The Russians view the Ukraine as an invasion route from Europe - which has happened several times in the past couple of centuries. The two biggest examples of using Ukraine to invade Russia are Napoleon and Hitler - have you heard of them? .
