Firstly....... It is very important to remember who initiated the latest escalation in this tragically long conflict. It was Hamas. They did so with their invasion of Israel and their deliberate killing, raping, and beheading of innocent men, women and children. If you have seen the clips I have you will know that many did this with enjoyment. They did so knowing exactly how Israel would respond. They did so knowing that it would lead to the death of thousands of innocent Palestinians. They did not care, They did it anyway.
I am sure that we all agree that Israel has the right to defend itself and respond to such deliberate acts of murderous barbarity don't we? However, this does not give them carte blanche to break international rules of engagement. They rightfully have the moral high ground, but if they want to keep it they need to be careful about respecting those international rules. I believe there are examples where they have not, and I am not talking about individuals gone rogue. Some may make the point that Hamas does not respect said rules, but that is why they are generally regarded as a terrorists.
Regarding your point about Israels objective in displacing poor innocent Palestinian civilians, a tactic that has led to much suffering. Their objective is clear. By displacing those citizens they believe it will be easier to rout out Hamas who have a long record of using innocent people as human shields. It is not a tactic that I agree with given the huge suffering it causes. However, they are not looking to deliberately starve civilians in the same way Hamas deliberately murdered and raped in October. There is a clear distinction for people to see. However, that distinction means little to the poor people suffering on the ground.
As I said........ The whole thing is dreadful. It is made even more dreadful because I cannot see a solution to it. Many on here talk of a "two state solution" as some kind of cure all, but I do not think it will happen, and even if it did that would not be enough for the jihadists who will settle for nothing less than the complete destruction of the Jewish State of Israel.
There will be ebbs and flows in the violence, but it will continue to be the vicious circle that it has been for so many years. Tragic.
