It’s wonderful to have faith that God will defend us, or Israel, or whomever.
The reality of history shows that’s not true. For being the “Chosen People”, Israel went into captivity how many times? If it’s impossible to tell the difference between being “defended” and outright losing everything, then being defended by God doesn’t mean much.
Israel needs to defend itself, and I think they have a good chance to do that. But there are no guarantees. Iran is crazy enough to nuke Tel Aviv.
I think you intended that response to be addressed to ‘who knows what evil?’.
