2, What about an attack on nato involving many NATO 30 countries but battles in just one or 2 countries Would you consider this world war 3?

3 what else would you consider ww3 besides literally around the world or literally 50 countries?

4, how important is preventing ww3 n how do you think it should be avoided?
