I truly believe that antiwar activists should focus our energies on military recruitment. The empire will modify its militarism only if is does not have sufficient bodies and minds to run all its ongoing and contemplated wars. I believe so all the more strongly in light of the failure of our Democratic Congress not only to stop the war, but to stop the escalation of the war.
The best way to accomplish this is to overwhelm the recruitment system with decoy targets. Antiwar persons, especially youth, should contact their local recruiter and express interest in learning about the career opportunities that exist for them in the US military. They can schedule appointments, attend meetings, take tests, ask questions, whatever. The whole point would be to waste the recruiters' time and energy. An hour spent recruiting somebody who isn't intersted is an hour not spent recruiting somebody who is interested.
This form of activism is almost risk-free. A participant will not be doing anything illegal. He or she will therefore not risk arrest as with civil disobedience involving trespassing or "disturbing the peace" or withholding funds from the IRS. It is a "quiet" form of activism, unlike the demonstrations that sometimes scare or offend the non-political. It doesn't even require any organizing per se, because it is a do-it-yourself project. And the potential impact is much greater than, say, blocking a single recruiting station for a couple of hours or walking a few yards on the campus of the US military's torture school in Georgia.
I would analogize this to the 1960s shop-ins, in which activists would visit segregated stores in the guise of shoppers, load up their carts with merchandise, bring the carts to the register, and then say: "I have changed my mind...I have decided not to buy anything here because your store is segregated!" Yes, it was irritating to the relatively innocent counter-person, but the message was received at much higher levels as well.
I do not assert that military recruiters are the worst people on earth or anywhere near as bad as Bush, his cabinet, or the CEO of Halliburton, only that recruiting is where the military-corporate establishment is most vulnerable, the Achilles heel of the evil system, the place where we should strike.
