War is not a joke especially between countries that have nuclear weapons.
If one of them uses a nuclear weapon, the damage won’t stay limited. Many other countries will get affected, and a small conflict can turn into a world war.
Right now, the tension between Israel and Iran is serious. But a full scale war, especially a nuclear one, is still very unlikely. In situations like this, world leaders usually get involved to de-escalate things. That’s what has happened many times in the past diplomacy and international pressure help prevent the worst.
What’s really sad is that some people are actually hoping for war just so the markets crash and they can profit from it. That mindset is dangerous and shows how disconnected some have become from human reality.
Because in a nuclear war, no one really wins the whole world loses.
