Will Israel be allowed to finish the job?

As negotiations get underway for more pauses in the fghting in Gaza for the release of other hostages, it has to be asked: will Israel be able or allowed to actually finish what they started, the elimination of Hamas, rulers of Gaza? As each negotiation starts and finishes, that objective looks less and less likely. The reason is obvious. Gaza and the rest of the world, especially the US, are getting more and more accustomed to ceasefires and basically want them to continue for ever to help the Palestinians recover from the seven weeks of airstrikes and artillery bombardment, to receive humanitarian aid, and just to survive. If Israel approves one more negotiated hostage-release and then goes ahead with all-out war to kill as many Hamas fighters as possible and destroy their infrastructure in the south, they will face the risk of being condemned by the rest of the world. Hamas leaders knew this was how it would work out as soon as they started to release hostages. The more hostages released the more difficult it will be for Israel to restart the fighting because Hamas will hang on to just enough hostages to deter Israel from launching an attack in southern Gaza. It's a clever and deadly strategy. I don't see how Israel is going to win this one.
