is it really so dangerous?

Today, I got a call from the supplier who are going to delivery the documents of L/C to the bank in Palestine. Our compnay opened the L/C in there, but the headquarter of our company is located in Israel. The supplier said DHL and FEDEX can not take the documents to Palestine due to it is too dangerous in Palestine. I can not understand it, seems it is peaceful in Palestine now. Why even DHL and FEDEX are not willing to do business there. but they do in Israel.

Is it really so unpeaceful in Palestine? I know it was, but I thought it have changed the turbulent situation now. Anyway, hope the whole world be peaceful all the time.
