If they had succeeded it would have been God’s will. That’s WHAT THE VERSE SAYS.
You remind of that joke about the guy in the flood. He keeps declining rescue saying God will save him. He finally drowns and gets to the Gates and he’s confused, he doesn’t understand why God didn’t help him. God says “I sent 2 boats and a helicopter, what were you expecting?” The hand of God can take any form. That verse says that if a king is removed, whatever the mechanics of it were, that was God.
Success is not always an indcation of God’s will behind this or that great deed.
So with regard to 2020: is that God’s will or is retribution coming?
