Is God really jealous?

I remember that suggested in the Old Testament report of the gift of the Ten(15, if you are a Mel Brooks fan) Commandments. One result was the military campaign of Joshua, where the Israelites understood they were to slaughter every man,woman, child and cow in the "Promised Land". The result has been a thousands of years of bitterness we still see in the Mideast. Are we to believe that God does not love his whole creation and want us to live in his respect and peace our cocreatees? Maybe the idea of a Triune God, with the promise of the Holy Spirit, who communicates to all, including Buddhists, Muslims, common to many faiths, should be explored, respectfully of course. See, I am not being a deliberate heretic here, but if we loved all our neighbors, might there not be the new millenia of peasce on earth, good will to all? Anyway, this was not a revelation received on top of a mountain, but at about 15 feet abovote sea level on the wrong side of the San Andreas fault. Thus part of my faith is that I will not be aboard to fulfill Curt Gentry's prophecy that land to the west of the fault will slide into the Pacific. See, my love, not all Norwegian thoughts are dark!
