It makes sense to have drills right now, India (tests with war against China and Pakistan), China (Telling their soldiers to be prepared to die for China), Russia(tests against Nato), and North Korea (getting ready for war with the US) are all having military tests for basically what will quickly become another world war.
We are really at a big crossroads as a large amount of people are rejecting globalization in many different countries. And with such major powers willing to fight hard for resources like Ukraine, South China Sea, Oil Eu pipelines, and not even mentioning the increasing gulf between various countries on core ideologies and creeds.
We really are at a new and dangerous crossroads.
