Deuteronomy 7 - God's Earthly Justice Through Earthly Judges

God's plan works out through the hands of His people on a regular basis. This truth has led to justifications of things such as the crusades in the past, but I feel like people are often gaslit into the idea that just because something like the crusades occurred in the past that this is no longer true about God for some reason. There is a very undeniable common thread throughout the Bible of God using the armies of one nation to exact judgement on another nation. Did God change the way He works randomly? Or did we allow the world to change the way we want to perceive things because of the way it has tried to blame Christianity for all the violence in the world and our desperation to try to justify God through a human perspective? To be clear, this does not justify any kinds of senseless innocent civilian death by the hands of Christians as if it is in the name of God or something. It is simply to say that we need to be extremely careful and consistent when considering the reasons that God may have for certain events.

The idea of self-defense works similarly in this way. If God never intends for us to defend ourselves in individual or family safety situations and instead wait on Him for an explicit miracle such as giving the violent attacker a heart-attack on the spot, does that mean that a nation or locality must wait for some miraculous external means for a tyrant to be brought down from power? Of course it does. But that isn't the consistent standard we hold today when compared to the majority of human history before us. Was it a random new revelation of super Christian ethics from God that came about in the 1960's that was never present in the previous 3000 years? Or could it be a worldly view of what governmental/judicial justice is having been co-opted by the West in a time of relative peace after the wake of two World Wars?
