You are right, it does take someone special to fight evil. More important it takes that one special leader to recoginize evil, then rally his people to defeat that evil.
Chamberlin," peace in our time" was not that leader. Winston Churchill was. And he met the evil of Hitler headlong, not with compromise, or treaty but with war.
Does the women in the garden have the power of Churchill, or President Bush? She does if she wants to. All she has to do is stop digging in the garden long enough to realize that there is evil all around her, and she can stop it just by lifting her head out of the garden(sand)to realize it.
Again, it is hard to stand up to a cruel totalitarian regime. Look at what Saddam did to such people.
