On Saturday I was not watching news feeds. I did not know that USA has started an attack on Iran. I found out just in the evening when my wife told me.
If she did not tell me, I would have probably found out today in the office. Because it impacts some of our businesses in the region. But if that was not the case, maybe I would not hear about it.
Would it matter? No. Just as dozens of other conflicts happening right now do not matter. Or to be more precise, they matter for a lot of people and matter for the future. But it does not matter if I know about them immediately. It changes nothing.
Most of the human history most people did not know about most conflicts and wars.
