Do you think there will be a third world war?

While anything is possible, we live in an age where war on that scale is unnecessary. Espionage, technology thief, disinformation & propaganda, social engineering and education is where wars happen now. However, I foresee a 3rd WW if smaller countries initiate it and the super powers get involved. For example, Iran attempts a nuclear strike on the US, I can see China and maybe even Russia building forces to protect them from retaliation, sparking a WW.
