I may address your points after, like how Syria attacked Israel illegally, therefore lost the Golan. Or how after Egypt's illegal attack and subsequent loss of the Sinai, which Israel later gave back for peace, or Israel's unilateral withdrawal from Gaza, proves that Israel doesn't "take every inch of land they could since 1947."
Since it came first though, will you admit that Israel's killing of approximately 39,000 Palestinians and Arabs (from the surrounding countries) in the wars, is hardly the same as what you said; "killing as many Palestinians as they can." That it pales in comparison to the 11 million Muslims killed mostly by other Muslims in the same period? (1950 to 2014) And that the Palestinians have killed about half as many Jews too?
Please forgive me, you're right, you didn't call for murder, though the difference between it and your hypothetical lack of sadness is negligible, and fascinatingly, just under the bar for incitement.
Israel's loss of land, as well as it's history goes back a few thousand years before 1947...
