Lie.

It's lying that has got us into this mess in the first place...so why not play by the game's established rules? Beats becoming a tool in a war you don't believe in.

I imagine there are many regretful young servicemen and women who signed on in the wake of 9-11 who never dreamed they'd actually be called on to serve active duty. You have done your part. If you object to serving on conscientious objector grounds, can they still arrest you? I can't imagine every nation's mailitary does not have provision for this.
