The countries where wars are likely to break out are in Africa, the Middle East and Asia. The African continent is an area that has seen a lot of violence over the years. A number of conflicts have taken place in Africa and some have not been resolved yet. One example is the civil war in South Sudan which began in 2013 and has caused thousands of deaths. The warring parties signed a peace agreement last year, but it is still fragile because there are conflicts between different groups within the country.
In Asia, there are many ongoing conflicts as well such as the one with North Korea and South Korea, or tensions between India and Pakistan. In addition, there's also conflict between China and Taiwan which has been going on for decades now.
