joseph, on a differnet thread, I agreed with a quotaiton you brought down from R”aharon Kotler zz’l, (see thread).
On this thread, I could not disgaree with you more. We just read , a few weeks ago, parshat Vajishlach and you know the Rashi as well as I. There are three ways to approach enemies and they include ALL. Doron- negotations, tefillah- prayer but ALSo milchomo. So, it is totally wrong to say that tefillah is the only way.
