Answer:
If WW3 were to happen it would remain as a conventional war without the use of WMDs. The major nuclear powers (US, UK, France, Russia, and China) will do whatever they can to ensure that nukes don’t get used.
At best, it will be a conventional war that has all the participants keep the scope of their military actions limited.
At worst, it goes nuclear and the map gets redrawn in a big way as many national governments cease to exist and their nations collapse. Fortunately we’re no longer capable of wiping ourselves out. A lot of people will die, but it won’t result in the extinction of humanity.
Wars start through any number of pathways: One world war happened through deliberate action, the other was a crisis that spun out of control. In the coming decades, a war might ignite accidentally, such as by two opposing warships trading paint near a reef not even marked on a nautical chart. Or it could slow burn and erupt as a reordering of the global system in the late 2020s.
Making either scenario more of a risk is that military planners and political leaders on all sides assume their side would be the one to win in a “short” and “sharp” fight, to use common phrases. It would be anything but.
A great power conflict would be quite different from the small wars of today that the U.S. has grow accustomed to and, in turn, others think reveal a new American weakness.
Answer:
Even though modern geopolitical relationships are difficult in a hypothetical world war scenario the world would be divided into direct participants, indirect participants, and neutral countries. The U.S. Making use of all its alliances all over the world including, North-American countries, Latin countries, Israel, former Nato countries, South-east allies, and African allies.
Explanation:
The modern geopolitical organization of the world would separate the world countries into three groups. Direct participants, indirect participants, and neutral countries. However, I can't say right now who would participate directly or indirectly because the starting conflict could involve countries that have never participated in a single war. However, I can tell you which alliances would rise. The NATO members. The Southeast Asian countries. The Asian-American countries in the Nato alliance. the Chinese-North Korea alliance and their sympathizers in Asia and the middle east. The seven Arab states and their sympathizers. The Russian-former soviet alliance countries. The South-American alliance. The African alliance. The African-Chinese sympathizers, the Latin-American Russia alliance. The U.S. Would ally with the south-east Asian countries, the NorthAmerican alliance, nato, and the African alliance.
