And Jesus told us to occupy until he comes. You also must read the Book of Revelation - nations shall be judged - the sheep versus the goat nations depending upon how they treat Israel. God judges sin, however, he also holds nations accountable. America has been the best friend Israel has ever had - with a few exceptions in the past 8 years.
And, yes, God says righteousness exalts a nation - unless we vote in righteous people, this cannot happen. Regardless of what some think - we are to be involved in our country’s political scene.
God is going to destroy every nation in their current form eventually (Save Israel).
He’ll hold them accountable as you say.
I find it interesting that when the Ezekiel 38 attack happens on Israel however, America is nowhere to be found with her defense. That suggests something major has happened prior to that attack.
