What are your thoughts on Peace and Justice today?

In his article "Father’s Day, Masculinity, and Peace" impeachment advocate David Swanson writes:

This Father’s Day, let us honor the men who have cared for us and for others, and the men who have worked hard and courageously for peace. Let us condemn the actions of men who have sent children (usually other men’s children) to war. Let’s shun them from the ranks of masculinity. Let’s go so far as to drop participation in war from the realm of admirable male behavior. Real men, let us tell each other, do not kill. Being a father is what actually requires balls.

What are your experiences or observations about the relationships between men, violence, and peace?  What solutions do you envision or practice?
