I agree that we need to seek God’s forgiveness. However, I do believe He expects us to fight. Look at Daniel 11:30, US is at least a candidate.
Of course he expects us to be ready to fight. I am not so sure that the battles we pick are the ones that are “in His will”. As someone says often, we can only claim that “God is on our side”, it doesn’t make it true. We need to be on Gods side.
