Very nice! I believe it would be stronger if you let the facts speak for themselves. Take out anything where you make come to an emotional conclusion. You have strong arguments. You don't need to lead the witness like I do in many of my pieces ;)

Also, think harder on the title. Always tries to go shorter and go for interest, not to summarize your piece. So thinking off the top of my head.

Like Bosnia, UN Stands Aside While Women and Children are Killed in Gaza

Did the UN Save A Single Life in Gaza?

Nothing Wrong With The U.N. That The U.S. Doesn't Make Worse

UN to Gaza: Drop Dead

U.N. To Gaza: Sorry, But U.S. Has Gun To Our Heads

etc. etc.

Again, great story! Any story where I learn something is appreciated!!!
