Have you read the IDF warning to the citizens of Gaza? I find it pretty unlikely, else you wouldn't make a claim as plainly false as "there is nowhere to run". This particular warning is about bombing a very specific region of Gaza that has a large number of terrorist tunnels in it. There are plenty of places "for them to run", as you put it -- quite literally anywhere other than that specific spot.
Regarding Hamas' origins, while this story makes for an excellent straw man, it's not particularly relevant to the question of deceptive statistics. It's also some remarkably dishonest journalism -- it manages to go from "an Israeli official admitted to giving some money to Hamas" to implying that Israel essentially started the organization. All the while, it very conveniently neglects to include any sort of information that might give a sense of scale. Not to mention, it conveniently neglects to mention that all the rival factions to Hamas were also terrorist groups at the time (Fatah only renounced terrorism after Israeli support of Hamas, and the PLO continues to engage in acts of terror to this day).
