Interesting…somehow these issues never go away. Not major in themselves, but expanded to critical mass by the participation of so many other interests.
It’s good to remember that Turkey was heavily involved then and has always been lurking at the back as a cause of European wars.
Something rather interesting happened a couple of years ago: the Patriarch of Constantinople recognized or confirmed the Ukrainian Orthodox Church as an autocephalous (independent “self-headed”) church not under the Moscow patriarchate. The action seriously annoyed the Russian Orthodox Church (and Russia). This of course also involved all of our favorite players, that corrupt band of nationalist politicians that were enriching Hunter Biden and the Big Guy.
It’s not the key issue, but it is part of the background and the fact that the Patriarch of Constantinople very recently made a statement (considered provocative by the Russians) reaffirming the separation is worth noticing.
Once again, we see the usual European powers and Turkey, with the addition of the bumbling US, poking the bear.
Another thing to bear in mind is that any war that weakened Russia would strengthen or even give domination to China.
