Which brings me to this fable:
A Wild Boar was sharpening his tusks busily against the stump of a tree, when a Fox happened by. ... "True enough," replied the Boar, "but when danger does come there will not be time for such work as this. My weapons will have to be ready for use then, or I shall suffer for it." And, suffer Ukrainians will.
At this writing on Thursday morning the status of the invasion is not very clear. I heard one report that there was movement on three fronts (which is what I predicted). Remember that the first report is almost always wrong.
The next major decision for Ukraine and its people and leadership is, "Do we defend Kiev?" They can make the Russians pay a very bloody price if they choose to make the Russians take the city by force. Or, they can declare it an "open city" and live under Russian domination for the next 40-60 years. My next door neighbor prefers the latter, since he points out the domination will eventually fail.
The other decision for Ukraine is, will they fight an insurgency war? Their choice.
I can tell you that any Eastern European countries are thinking that joining NATO—looks like a really good idea!
