“ Here’s a list of Islamic extremist attacks since the 1960s. Take a look at the list of countries. It’s pretty much every country on Earth.”
Its nowhere near ‘every country on Earth.’ It is almost exclusively limited to Muslim majority countries, countries with an oppressed Muslim minority and countries that have intervened politically or militarily in Muslim countries. ‘Terrorism’ has causes.
There are 53 countries listed in the Wikipedia list. Currently there are 195 recognised sovereign countries.
Stick to what you know.
