It would be a logical fallacy to jump to such a conclusion without interviewing a randomly sampled and much larger population. It is possible you may be correct or incorrect, but you are jumping to a conclusion about a topic with insufficient data to do so.
Your evidence supports that there are members of the IDF who are enthusiastically engaged with what they’re doing. I am not debating that- i think you’re right.
But it’s important to remember this absence of evidence is not evidence of absence. Just because you haven’t seen interviews of IDF members objecting to what they are doing does not mean those members do not exist. I would expect the IDF to have systems in place to minimize the external visibility if any such objections, which makes a generalization like that dangerous.
They aren’t going to let you see the unenthusiastic ones.
The beautiful irony here is that you are believing in and spreading IDF propaganda for them.
