Mate we were literal children during these events.
My literal 7 year old niece knows about both the Israel-Hamas War and the Ukrainian War.
I duno how old you were, but lets say 3 years after the Rodney King riots of 92? So lemme pick a random 1995 event. Were you aware that Israel Prime Minister Yitzhak Rabin was assassinated when you were 7? Something I do remember was the USS Cole bombing. Do you remember that? That happened a bit later, Wikipedia says 12 October 2000.
The issue isn’t “we were children”. The issue is that research and information was far more difficult back then. Newspapers cost money and required manual reading. (Though I was able to pickup a few Newspapers when I was waiting for a haircut or other such events). We didn’t have online forums (well, ignoring BBS and USENET)… or at least online forums weren’t popular. And internet was very expensive and slow back then. So we didn’t get information anywhere as quickly as children today get information.
Secondly, it wasn’t “cool” to be politically informed before 9/11. That was just nerd shit back then. 9/11 changed our collective mindsets and everyone became more aware of world events.
