The 10 commandments were written to both men and women.
Some apply to men, some apply to women, most apply to both. Do you think the one about not coveting your neighbour's wife was directed at women?
The concept of adultery committed by men simply didn't exist back then.
And because of what Abraham did (going outside God's will for him) we've had war between Abraham's seed ever since.
But there hasn't been.
It's important to realise that there hasn't been a war between Jews and Arabised Arabs (Ishmaelis) ever since. The war started in the late 19th century when modern nationalism reached the middle east and transformed a tolerant Muslim society into a dangerous pan-Arab national-socialist empire. (It's the same force that transformed Europe's land of thinkers and poets into Nazi Germany.)
The first we hear about Ishmael's offspring, the nation G-d made out of him, since Abraham's death is what Muhammed told. Muhammed's tribe was, so they claim, the descendants of Ishmael's. And Muhammed thought he was a prophet (or was a prophet sent to the Arab peoples, it doesn't matter, since what he taught was based on the Bible anyway).
And here's what Muhammed and his followers did and said with regard to Isaac's offspring, the people you think he was in a war with:
1. Muhammed confirmed, in the Quran (a word that means "recitation" or "reading" and refers to the fact that Muhammed's prophecy was a reading of earlier scripture, i.e. the Bible INCLUDING "New Testamant") that G-d sent Moses to the Children of Israel.
2. Muhammed confirmed that G-d, via Moses, liberated the Children of Israel in Egypt and led them to their promised land.
3. Muhammed confirmed that the Children of Israel received the promised land from G-d and had a right to live there.
4. Muhammed founded the first Islamic state in Medina with a constitution that regarded the religion of his followers and Judaism as equal and the two peoples, Jews and Muslims (i.e. those Arabs and Jews that believed in his prophethood) as allies against Arab pagans.
5. The caliph Umar, when he took Jerusalem (from Persian rule), went to the temple mount and built a mosque there.
6. Umar also called on the Jews in the world to return, claiming that their "exile is over".
7. Under Muslim rule Jews were not usually persecuted (until the fall of traditional Islam and the rise of Arab nationalism), as opposed to their status in "Christian" states and empires.
8. Later Muslim rulers gave refuge to Jews who fled "Christian" territories. The Turkish emperor even sent a fleet in 1500 to collect the Jews of Spain whom the "Christian" rulers exelled (and before that persecuted and tortured). The Spanish Jews (Sephardim) have had a stronghold in Turkey (in Istanbul and Thesaloniki) ever since. (Morocco also granted refuge to Spanish Jews. Even today a representative of the Jewish community is part of the government, and yes, they can emigrate to Israel or visit Morocco from Israel.)
9. The Hashemite family, descendants of Muhammed's uncle, rulers of Iraq (until the 1950s) and Jordan, made a deal with the Zionists that was supposed to (until the Nasserists and other Arab and Syrian nationalists started the attacks) create an Arab empire with a Jewish state as a connection to the western world.

Note that King Faisal, Ishmael's descendant, didn't think of Palestinian Arabs as Arabs and held them in much disdain. Faisal saw his Arab tribe and the Jews as the one side and Palestinian "Arabs" as the others. Note that Israel and Ishmael stood together against the others until the others became too strong (not without German help). Then, and only then, did the descendants of Ishmael join the other Arabs against the Jews. But that was in 1948.
There is no traditional "war" between the children of Jacob and the children of Ishmael.
However, there has been a traditional war between Christianity and Jews, with Christianity trying to murder and torture (and forcibly convert) Jews that only ended a few hundred years ago (in Ireland the earliest within the British Empire, and in Germany and Poland the earliest within the entire Christian world).
That is not your Christianity, KFC, but it was the face of Christianity for over a thousand years. Your form of protestantism "protests" exactly that feature of nominal Christianity. You explained that to me in the PM, remember?
Abraham did nothing wrong and there is no war between his two sons and their respective nations.
Ishmael's descendants were to assume the role of protectors of his younger brother's descendants. And despite minor and major disasters they have fullfilled that role MUCH MUCH better than those who claimed to fullfil the "Old Testament" by replacing its laws with the "New Testamant".
Abraham did nothing wrong and his two sons (the two we are looking at here) had their own destinies and it took until over 3000 years later that their descendants fought their first major war against each other. And that war was started not by either of them, but by an ideology that developed in the Christian world.
