You make the point that "You can withdraw your civilian population out of the range of homemade missiles and continue to use non-lethal methods of coercion." If you withdraw outside of range, Hamas won't be satisfied, they will instead expand the range, and this is what has happened. Hamas been supplied with longer range missiles by Iran. From the safety of suburban US we can decry the loss of innocent life, but if my house was taking incoming shells, I would demand protection, not relocation.
As for your contention that Israel is the only source of information, the way that the press has been spun by the Palestinians in the past has led the Israelis not to trust the press. Remember the "thousands of deaths" in Jenin, turned out to be 38 fighters? Remember the Al-Dura hoax, until it was proven that if the boy were shot, it was by the Palestinians, after anti-Israel riots. Led by the anti-Israel BBC, which won't even release its own report on anti-Israel bias, Israel has no reason to trust the world press.
