Maybe isreal could give back the land they stole and murdered for and quite trying to expand there territory into egypt. Then everyone could live in peace.
They're not trying to expand their territory into Egypt, and they didn't steal any land.
Aside from the land purchased by Jews from Arabs (for outrageously high prices), many of whom were absentee landlords who owned useless and undesirable land, any land taken by Israel from Arabs was done while Israel was defending its very existence from people who would attempt to annihilate Israel.
All Israel wants to do is live in peace, side by side peacefully with its Arab neighbors.
Unfortunately, none of the Arabs want Israel... none of them acknowledge Israel.... and Palestinians have stated in every one of their political charters, in some way or another, that their intent is to destroy Israel.
Israel's declaration of establishment explicitly states the intent to live peacefully among its Arab neighbors. PLO, Hamas, Fatah... all founded with the intent to destroy Israel through armed struggle. Hamas doesn't even stop with Israel... they want to see the death of all Jews anywhere they exist.
The cause for this conflict is the Arab refusal to accept the existence of Israel as a legitimate state.
The solution for this conflict is the Arab acceptance of the existence of Israel as a legitimate state.
Everything else is details.
