Yes, if "context" was oh-so important, why would a god want (a sizeable chunk of) their last word to their creation to be the war diary of one general, with everything having to be read in the "context" of one, specific war?
Also, if he had meant 9:5 to apply only to the battlefield, it is only three extra words to say "wherever you find them… on the battlefield".
Just three words to transform it into something roughly equivalent to Christianity: be nice to people all the time but, when blockheads insist on declaring war on you then you are permitted to kill them, in battle. Go back to being nice after the war is declared to be over.
On its own "wherever you find them" sounds like they should scour all the corners of the earth.
Again, if context is important, it would be helpful to know if Mohammed knew anything of the wider world, beyond the bounds of Arabia? But what Muslim scholar would dare say that he was a parochial ignoramus, who'd (maybe) seen Roman ruins but never set eyes on a Roman (Byzantine, by his time) or who had only vaguely heard of the Levant?
If the context is the Mecca/Medina wars and it was *always* meant to be peace, after that, then all the Muslim expansion beyond those two city states could be regarded as un-Islamic and, in essence, imperialism.
