Why lies? If you wish, I could provide you with proof that I am currently located in Israel. Most likely an IP address.
I know they can't go into Israeli territory, but you forget that Jerusalem is on the very edge of the palestinian areas. I have both an american and an israeli passport, so I can venture into palestinian territories as I wish, and, having participated in an interfaith programs to promote peace in the area, I actually have met several Palestinian people and know them well.
While I have never been inside Gaza, Israel did not destroy Gaza any more than the US destroyed Iraq and Iran. Civilian casualties are an inevitable part of wars inside cities. However, there was good reasoning for the attack. Imagine 60 missiles landed in your neighborhood every day, for several years. If that happened to the US, imagine the consequences.
What non-UN approved weapons were used? White Phosophorus is approved as a smokescreen, and while several soldiers have used it against regulations, the army never had the intent to deploy WP in an illegal manner.
Either way, People who live in Gaza are not severly lacking in Food, water, or many other things. Gaza is known to be infested with tunnels to egypt, which means that smuggling is abundant, and Israeli aid is more than enough to supply people in gaza with plenty of food, water, and clothing.
Read This. The worst problems in the area are, quite simply, that Hamas is a terror organization.
