Declare Victory and Retreat
No. That's not a strategy for Iraq, that's the strategy of of people who claimed that research on embryos derived from human fetuses was necessary. As long as they're retreating, we don't have to shout that that part of the ESC research that was necessary could be done on stem cells from animals. (We should whisper it in order to let them know we can counterattack if the retreat stops.)
Some of the opponents of ESC research will also have to retreat since some of them are opposed to life extension in general. I doubt if there are that many of them.
