I'm from Egypt, so my country was on the other side of colonialism, but that's irrelevant either way.
Imagine if after 9/11, the Taliban had said “we want peace now”, would you or any other American have accepted their peace overture?
The Taliban didn't do 9/11, but that aside 9/11 and this attack are fundamentally different. A closer comparison would be terror attacks against Britain during the Troubles.
