War between nation-states, or with factions willing and able to use explosions as weapons, may require explosions.

However, there is a duty to not be a complete fucking idiot about it and invade a country that had nothing to do with the explosions that happened to your country, killing thousands or more, destabilizing the region, and creating the environment suitable for the rise of a violent theocracy.

If one cannot pass this very simple hurdle, one has no business using explosions for any purpose.
