I'd like to change the wording slightly to "on US soil, or on a flight to or from the US" if that's alright with you (even though I think an attack on an aircraft is less likely than an attack not involving aircraft). A poll here sounds like a fair way to resolve any dispute. I expect to still be reading/posting here fairly regularly in a year but I'm also happy to provide my email address if you want.
Could you email me so I have your address too? paul at ciphergoth.org. Thanks!
I would like to propose this as a thread for people to write in their predictions for the next year and the next decade, when practical with probabilities attached. I'll probably make some in the comments.
