Does God Care about Politics?

Is Jesus King of Nations? Or is He only King of individual hearts? Does God care about national and global politics?

"Righteousness exalteth a nation: but sin is a reproach to any people." -- Proverbs 14:34

"The king's heart is in the hand of the Lord, as the rivers of water: he turneth it whithersoever he will." -- Proverbs 21:1

"When the righteous are in authority, the people rejoice: but when the wicked beareth rule, the people mourn." -- Proverbs 29:2

"Blessed is the nation whose God is the Lord; and the people whom he hath chosen for his own inheritance." -- Proverbs 33:12
