I keep reading this. Is it plausible the Netanyahu government cannot secure their release some 22 months after the fact? Are they going to keep repeating that line until tens of thousands of people die of malnutrition and Israel comes under international sanctions?
Resolving Hostage Crisis 101
Step 1: Captors release hostages.
Step 2: Kill 'em all if the hostages aren't relased.
The Israeli's let this drag out too long. Netanyahu maybe stetching this out for his own political reasons.
The prudent approach would have been to reduce every sqaure inch of Gaza to smoldering ash. Western bleeding-heart liberals will weep for a starving baby. But if there is only smoldering ash, they have nothing to weep for.
Hamas needs the West to see starving babies and desperate mothers on TV to put pressure on the Israeli's to let Hamas survive to launch future terror attacks against Israel.
Gazans need to choose between saving themselves versus saving Hamas. Hamas embeds themselves among civilians to use them as human shields. Hamas weaponizes decency, humanity, and charity to live off the land and to draw in new Western targets for attack and kidnapping.
The world will be a better place when Hamas has been wiped from the face of the earth. The Gazans can choose to perish with Hamas or to flourish without them.
Who won't Hamas kidnap, rape, and murder? They are Evil.

These are the same bastards that flew planes into buildings on 9/11/2001 and that killed and maimed spectators at the 2013 Boston Marathon. Radical islamists will kill us all if given the chance.
At any point, the Gazans can choose to get off the Hamas merry-go-round of terror and suffering.
