This is kind of interesting actually. It suggests that Israel's propaganda department (or whoever set this up) is stuck so far up their own ass that they think the only reason someone would go against them is because they don't know how "evil" Hamas is. Reminds of a certain early 20th century central european nation, and how they treated their own nationalism and expansionist projects...
Though I imagine this "horror footage" is going to be play at insanely loud volumes 24/7 to deprive them of sleep. And them saying it will teach them about the horrors of Hamas is just an excuse the western media will parrot when in actuality it is just going to be used as a torture method to force them to sign some documents that state that Hamas is evil and they were wrong to support Gaza and Israel is completely innocent of any wrongdoing. Israel is going to do whatever they can, no matter how fucked up, to try and turn this to their advantage. It will be obvious that any admission of "wrongdoing" here will be under extreme duress, but the western media is never going to report that side of things.
