In the end, the only, and I mean ONLY, way the American people will ever act on self preservation or protest as a whole, is if the pain and suffering actually makes it to them and theirs.
You can't just warn them this oven is hot, you need to throw them into said oven and turn it up to full blast. Only then will they kick and scream and fight to save themselves.
Nothing less will do, nothing else will work.
