Yes, our leaders are responsible for their actions and for how they lead a nation. But the people are responsible for their leaders in as much as they select those that lead them. Our great sin is to desire and trust in a human leader more than the true King that deserves our honor and service. The Lord will yet bless our nation if we would repent and turn to Him.
Now therefore, here is the king whom you have chosen, whom you have asked for, and behold, the LORD has set a king over you. “If you will fear the LORD and serve Him, and listen to His voice and not rebel against the command of the LORD, then both you and also the king who reigns over you will follow the LORD your God. “If you will not listen to the voice of the LORD, but rebel against the command of the LORD, then the hand of the LORD will be against you, as it was against your fathers.
1 Samuel 12:13-15 NASB
