The fighting goes unabated across Ukraine. It is too early to tell if and when this war will end. But we can still learn many lessons from examining the course of events.
Ukraine agreed to get rid of all the nuclear weapons that the former Soviet Union left behind, after the collapse, and it became a nuclear-free country. If they had not done that, Russia would have thought twice about attacking. But this made Ukraine a sitting duck for takeover. And if the free countries of the world had come to Ukraine’s aid, with troops on the ground, again President Putin would have had to reconsider his strategy.
