Well, don't take this the wrong way... I'm not making a claim here one way or the other, but simply for the sake of argument... IF the Israeli government (as opposed to some individuals within the government) had genocidal intent, do you really think their official policy would openly state that? No, that would be a foolish thing for any government to do.
As for your last paragraph, I think you and I talked about this on another thread. While what you're saying sounds good, and is what we hear from the MSM, I have heard numerous conflicting reports in regard to all those things you mentioned. And not from Israel's enemies, but from a number of organizations that are more neutral, like Doctors without Borders and others.
Again, don't get me wrong. I'm not making any definitive claims or taking a side, but when it comes to war, I take everything I hear with a grain of salt.... and I am not guided by tribalism, partisanship or anything like that. To me the only thing that matters is the truth. And as the saying goes, truth is the first casualty of war.
