The Ukraine-Russia war may well inflict a blow on the global economy from which it won’t recover. From The Zman at thezman.com:
It is assumed that the worst case scenario for the Russo-Ukrainian conflict is the direct or even indirect involvement of NATO in Ukraine. If NATO forces came into direct conflict with Russian forces, the result would be total war and total war could easily and quickly lead to nuclear war. This is a remote possibility as NATO has been adamant about not getting militarily involved. The West is content to use the economic weapons at its disposal that it assumes the Russians have anticipated.
While there is nothing worse than nuclear war, the fact that it is the least likely outcome means it is not the worst probable outcome. The fact is, the Cold War was a good lesson in the use and non-use of these weapons. Nuclear weapons are last resort defensive tools. A nation will use them as a last gasp at survival. This is why Israel stole the technology from America in the last century. It is why North Korea is developing the ability to deliver a nuke to North America.
If nuclear holocaust is off the table and a wider scale war in Europe is off the table, then that leaves the softer, less predictable outcomes. We are already seeing big ripples in the financial markets as people try to figure out the downstream consequences of the economic sanctions on Russia. Despite what the media may claim, Russia, Belarus and Ukraine are not hermit kingdoms. They have a lot of economic links to the rest of the world and are a vital part of the global supply chain.
