I am also not convinced that executing the POWs will help, but that being said i think you’re overestimating the degree to which international opinion has any ability to impact this conflict whatsoever. It has been clear for a while now that neither the occupation regime nor its international allies care to mask their brutality anymore. They are not concerned about what anyone else thinks because they believe no one can do anything to stop them. And frankly i think at this point Palestinians just don’t and can’t afford to care anymore about the optics of their struggle either. It is life and death for them and they have to do whatever it takes to survive.
The only slight parallel that can be drawn is between Gaza and the Donbass Republics. Ukraine attempted to cut off Donetsk and Lugansk (as well as Crimea but the Russians were able to resolve the problems there fairly quickly) from access to water, electricity, pensions, banking, etc. They also held these republics under siege since 2014, and continue to constantly shell civilians almost every day. But that is where the parallels stop as the situation for Gaza is infinitely worse in every respect. The Donbass had all of Russia behind them and could never be completely cut off, they were much better armed and dispersed over a larger area. And now they have received the direct help of a very powerful military and are able to fight and win a conventional conflict. The people of Gaza have none of these advantages, they will have to continue to rely on highly asymmetric tactics and guerilla warfare. And the civilian losses will be orders of magnitude higher than in Ukraine where the Russians have been extremely cautious.
I think while the situation in Ukraine is starting to look very optimistic and we may see a positive resolution as soon as next year, the situation in occupied and besieged Palestine is much more difficult for the foreseeable future. It will be a brutal, prolonged struggle and it will be very painful to watch. Do not expect a quick victory. There will be many tragedies and losses along the way, we have to steel ourselves for setbacks and news of horrific atrocities committed by the Zionist entity, but in the end i have faith that the forces of the Resistance will prevail. The global balance of power has changed too much and it has changed irreversibly against the US. Both the US and the Zionist entity are weaker than they have ever been in the entire history of the Palestinian conflict. The Resistance did not fail to take notice of this and to take it into account when they chose to make their move with this daring break out which has escalated the conflict to a new and unprecedented phase. They have allies across the region and they have surely planned, coordinated and prepared to wage this struggle and to come out victorious.
