You are really changing the subject from aggression, but...

Let's say we have a dispute. You say I stole your house, and I say I didn't. Do you think a good way to resolve the dispute is to take pot-shots at my kids? Does it make it a better idea to take pot-shots if I have a machine gun and you don't?

As far as I can tell, defending Hamas is just insane, even if you really, really think Palestinians are abused by Israelis.

No, that's bunk. A more accurate representation is that my house is built on a plot of land that your ancestors had thousands of years ago. Your mates tell you that you can live there, so you come in and beat me up and kick me out and destroy all my shit. When I then try break back in, you shoot me and my family.

Huh, WTF? Israel is not occupying Gaza since 2005.

They are occupying the West Bank. I would have said Palestine, but I was using the words of the OP.

"Their land"... if there is something that the Palestina and Israel conflict has remembered us is that nobody owns anything that they can't defend. The Americans killed the natives and then future generations don't think that it matters because they weren't directly involved in that; the same thing happens in this conflict that haves already many years in the making.

People entitle themselves to land for no logical reason; nobody thinks: "This country haves 40 million people an there is 7.053 billion people in the world; therefore we should only own a 176.325th of the available terrain"; never happens.

By this logic I could punch you in the face and steal your phone and it would be completely righteous because you didn't defend it well enough.

What is the point of civilisation if it fails to prevent suffering?
