Since this war is all about money and power, protesters must speak themselves in the language of money and power. So one way I thought might be possible to do this, is on the day bombing starts, to withdraw a substantial amount of money from a bank account.
Banks are the real engines of the economy. Since reserves are the major variable in deciding how much money can be used for loans, an artificial "run on the banks" could be a drastic and frightening attack on the status quo.
Perhaps it's too much, really. But time is short. It would be nonviolent and legal. The threat itself would be intimidating. I am unaware of the risks, and would not advise anyone to do this without deliberation. But I wish to get the idea out so it can be considered, since time is so very, very short.
