Well, if you do not think that prayers will work. perhaps, it is the manner in which you are praying or the god to whom you are praying. I would suggest however that you send money to Israel so that they can rid Gaza of Hamas. This will allow the non-terrorists who live in Gaza, to live in peace. This will allow all the aid from Israel and other countries to be used for the schools, hospitals and such that it was intended for and not rockets and the building of tunnels. I think that this would be a good start.
