War is always about killing. So an orthodox jew would be Legally (with a capital "L" ) compelled to do triple back-flips to placate and resolve the situation instead of killing. In fact, technically, an orthodox jew would have to allow himself to be killed rather than kill another. So also, technically, war would be forbidden for devout jews to engage in.
Now, Israel supposedly exists and is therefore contesting real estate with Palestine over DEVOUT RELIGIOUS REASONS. The only way they are allowed, within Yahweh's clear Commandment, to resolve those issues is by peacable means, or else lay down their own lives rather than kill for real estate.
Meanwhile as you say secular or non-devout jews fight and kill quite apparently for non-devout reasons over real estate. And how is it again we're supposed to back them for the sublime and devout reason of their occupation based on Devine Birthright?
I think having the assignments of orthodoxy living peacefully by secularism within the same jewish community is a gross distortion of the jewish faith. If they can live amongst heretics in the house next door, why then can't devout jews live next door to christian Palestinians without fuss? "Respecting" secular jews on the orthodox's behalf is maybe even worse than respecting Palestinians. Because Palestinians were born "not knowing the proper way to live" right? So an orthodox jew staring at the maw of a secular "jew" must do so knowing that person was raised to know Yahweh and then actively chose to turn his back on the faith and do all manner of sacrilige against the faith of the house they were raised in.
And there goes, By the way, "honor thy father and mother".
