This isn't very different from other major wars. Every war changes certain balances and the ones who always lose are the people. Just as what happened in Ukraine affected the world, Iran is affecting it as well. The war era will continue and we'll likely see other wars in the near future. It'd be good to be prepared for that.
I guess this Iran war would be very different from Ukraine -Russia war or any other conflict as this involves many countries and also the world oil supply is affected by this war. Due to this, this war will have a global impact and no county can isolated themselves and say that they aren't being effectee by it.
Also this war may not end as quickly as we think and it may last many months. I am really worried that we are heading towards World War 3, sometimes in the future.
