Please ask this question whenever possible:
"When you talk about peace, do you mean peace just for your team (yourself, family, company, race, nation, religion, etc...) by defeating, controlling, and dominating everyone else or do you mean peace for your team by living within a healthy and peaceful community of life?"
Living within a healthy and peaceful community of life is a grand and lofty goal, and certainly one worth aspiring to.
BUT: How do you deal with people who want to kill you, not for what you are, but for what you aren't?
Are you willing to discard your personal beliefs and embrace theirs, in the name of peace?
