Years ahead. Years.Going from bad to worse.
Will be a grim few weeks ahead
I am thinking they will take Ukraine by the end of March and then the Ukrainians will begin a guerilla insurgency that will last decades. It will be a low level war that will last decades. Assuming the war doesn't fully spiral out of control into a global conflagration.
I grew up hiding under desks in my elementary school in Montreal from nuclear war. This has a worse feeling.
