This post is not here to debate the stats or pros and cons of that war, but just to look at how it will change the political map of the world.
Every small action here , has ripple effects, which spread like ripples from throwing a rock into the farm pond.
Some are barely noticeable, other cataclysmic.
It looks like another "Iron Curtain" may be asserting itself in eastern Europe..a few hundred miles eastward of the old one.
Suppose the present "no fly" zones for commercial aviation, become permanent! Russia has a huge land mass, which if denial of commercial airlines continues...will make western airlines routes much more costly.
...But Russia doesn't get off easy either. Russia can fly over their homeland, China and likely parts of India, with Africa being a mixed bag. Consulting my globe while I speak...I see they cannot however fly over the northwestern quadrant of the globe..dominated by US and Canada . In fact, their routes would be severely limited.. Certain countries in South America, as well as Cuba, may welcome them, but they would have to fly a long, convoluted route to get there...perhaps not worth going..
Here is a non-partisan, history video that explains much very clearly.. Very educational.

Sad, that so much disruption is happening, when I look back to see how well things were going while Pres Trump held the reins for the USA !
