Sure. And yes, it's risky. But there are two million people in Gaza and half a dozen to a dozen, on average, being killed each day. If I, literally I, were teleported into Gaza, my primary operational concern would be avoiding Hamas. (My primary operational goal, getting to an internet-connected device.)

Correct, their security forces are undisrupted.
