My own country lost its mind after 2,977 people died in one terrorist attack a quarter of a century ago and we made many many bad decisions for a long time afterwards. It sucked. In October 2023 I had hoped that my country's well publicized example would help your country not make the same choices but it's hard to learn from other people's mistakes.
This is a false equivalence. 9/11 is not Oct 7 and the US is nothing like Israel, in fact the US was attacked for (amongst other things) it's support of Israel. America also did not conduct genocidal actions in the manner Israel has.
Israel is a colonial project that annexes land and homes from people against international law and has done so since it's conception. Gaza is a refugee camp of descendents of people displaced from their homes during the Nakba. There's a saying there: "My Grandmother is older than Israel" -- and it is true.
To look at Oct. 7 as some sort of isolated incident ignores the history of the project: After the holocaust Western Jews decided to move to an area already occupied by other people based on some loose notion of having claim to it millennia ago. They used western governments to push this concept forward. Sure, America displaced Native Americans, but Israel did it during modernity... and those natives also happen to have access to modern heavy weaponry... what did they expect to happen?
I think Israeli people are ingenious and talented but they picked the wrong patch of land to occupy -- the Al-Aqsa mosque in Jerusalem is as sacred as the Vatican and you have 1.5 billion (often crazy) Muslim people revolving around this sacred conceptualization. This is why the common people even of places like UAE/Saudi all back Palestine despite the political actions of such states. It is a recipe destined for disaster, especially with the Iran war de-coupling the Gulf States from the USA. It seems to me there is no way out.
America didn't do things like this after 9/11, we tried to build democracies in a naive way, failed, and got a lot of people killed unnecessarily. Iraq was completely unjustified and based on fabrications.
But we weren't trying to wage war against the entire civilian populations as revenge. That's an entirely different category of crime.
