I'm not talking about a small scale FF (mall shootings, etc.). I'm talking about something big, like 9/11, Pearl Harbor, etc., where at least thousands die.

I am using the term "false flag" colloquially, as a kind of catchall, rather than in in the strictest sense. For the purposes of this exercise, consider both Pearl Harbor and 9/11 to be false flag attacks.

What do you think it will be, based on the your gut feeling, evidence, other peoples theories that you think are likely, etc.? And where will it take place?
