Concerning the Russia / Ukraine conflict:
This post is not for everyone, but for those who are interested (and have the time) it does explain much about how and why we got to this point. It includes an explanation of how the Russians fight, and why Ukraine will lose this war.

After the fact, some ideas to consider:
Is it inevitable that the conflict leads to WW3? – No, it is not inevitable.
So it is not possible the conflict leads to WW3? – Wrong. It is possible.
OK, so the conflict is likely to lead to WW3. – It is a question of probability. Probably not. (fingers crossed)

IMO this is one of Daniel Davis’ best posts.
