There are some people in life who, upon witnessing an atrocity or crime against another person, will pass right on by. Perhaps they are afraid to get involved. Or perhaps they don't care.
Then there are others that would stop and try to help as best as they can. It's what's known as doing the right thing. If our tax money and our veto at the United Nations Security Council are harming innocent children and elderly people (among others), then it's time to seriously reevaluate our foreign policy, at the very least.
What would YOU do, if they came to take your land, kill your children while at school, destroy your home,
flatten your orchards, build a wall around your village effectively imprisoning you in your own land, or
tell you that you cannot return to your home because you are the "wrong" kind of person?
And when you try to go the world for help, and UN resolution after UN resolution is passed in your favor, but still nothing gets done, then what would you do? Would you give up?
