Isn't it fascinating how the threat of a domestic uprising stirs the creative problem solving juices of the benefactors of the status quo?
And, I would hope that people would consider what creative nonviolent disruption they could do, if this bombing were to happen. It is better to prepare and not need an action, than to wait until it's time to act and have circumstances pss you by. Opportunity favors the prepared. Also - the threat of such action keeps pressure on the decision makers, as the the threat of the unknown is actually more frightening to them than the known.
Personally, I think that if well orchestrated the Detroit traffic slow downs combined with with marches onto the freeways during MORNING commutes could be extremely effective at pushing "pause" on the War Machine. The thoughtful work to do this safely and in a nonviolent and coordinated way across the country should keep the fire under their diplomatic buttocks turned up to high.
