That tiny thought "they tricked us" is very important for the believers to have. It is a tiny dent in their force field against using simple logic for themselves, instead of following orders from their governments.
It will happen again. Not in the same way of course, that would be too easy for us to identify. Nuclear fallout incarceration, WWIII fervor, I think we are heading to war. Look at how many countries are opposing the US at present. It's all good.
I hope so. I really do. (That they wake up, not that we get to war, obviously)
