Well, it's worked a few times in history, what about in 29476?
How about it girls (and "girls")?
Lysistrata, a comedy by Greek dramatist Aristophanes (c. 447 - c. 385 b.c.e.), tells the story of a group of women from opposing states who unite to end the Peloponnesian War.
After matronly stormtroopers take over the building where public funds are kept, the women rise to end the war by withholding sex from their mates -- Until, desperate for intimacy, the men finally agree to lay down their swords and see their way to achieving diplomatic peace.

"Well Susan, I think I can answer your question, easily. War is a man's domain, plain and simple. Women are too compassionate for war, and FAR too ruthless."
