I would imagine most people see what they want to see. Im not sure its the IDF intentionally being misleading so much as them just being on their best behavior when they are under the eyes of a foreigner to some extent, and also just the fact that there isnt much to see other than the fact that they just dont let much shit in or out.
You see much more when you see starving uneducated kids in the street with no power because israel had, for months, cut the power to the area as a punishment.
