The current Iran conflict has basically already begun as the US President ordered an air-strike on an Iranian general. However, many people are saying that this is going to be “World War III,” and I’d like to say they’re wrong.
While the conflict might at the most end up in multiple countries forming a coalition to attack Iran, the chances of it catching the world on fire are basically zero. This is a US-Iran conflict, and although many countries have condemned the airstrike on Soleimani, they’re not going to declare war on the US.
First of all, attacking the US would be very risky. NATO would probably respond pretty quickly if you were to declare war on the US, which means that you have to fight NATO and the US at the same time just to stay alive, and nobody is going to want to risk that happening.
And if you do risk it and win, the casualties you’d suffer would be pretty high making it a pretty pointless and drawn-out war.
So no, it’s not world war III.
