Then we should make sure the war never ends.
Practically speaking, it doesn’t matter who wins. The winner will hate us, the loser will hate us. If we intervene, they’ll both still hate us. The longer the war goes on, though, the less of them there will be to hate us. Let the savages be savages.
It does not follow that there will be fewer to hate us, especially given their reproduction rate. It also does not follow that our staying away will mean they will stay away from us, since their imperative is eliminating the “great Satan”.
I don’t call for “intervention”. I call for crushing them, which is something that nobody in DC has the stomach for.
