With the current event happening around the globe; the spread of the corona virus that affected a growing number of countries, I don't think any country would not have the capability and time to enact a war. The war in oil have been going for quite a time but, I think this pandemic stopped it even for just months because, every country needs to focus more om the welfare of their people to survive the crisis.
Wars over natural resources occur periodically and quite regularly. Recently, we have witnessed increased military tension between Venezuela and Guyana, essentially due to the discovery of large natural oil reserves in Guyana. But due to dramatic climate change, wars may also intensify over the availability of fresh water, fertile soil and even food, if humanity does not quickly address the looming threat.
