There is not much peace because too many people do not know the Prince of Peace.
There is not much peace because we, as a nation, have sinned against God and have not walked in His ways.
"7O Lord, righteousness belongeth unto thee, but unto us confusion of faces, as at this day...because of" [our] "trespass that" [we] "have trespassed against thee. 8O Lord, to us belongeth confusion of face, to our kings, to our princes, and to our fathers, because we have sinned against thee. 9To the Lord our God belong mercies and forgivenesses, though we have rebelled against him; 10Neither have we obeyed the voice of the LORD our God, to walk in his laws, which he set before us by his servants the prophets... all this evil is come upon us: yet made we not our prayer before the LORD our God, that we might turn from our iniquities, and understand thy truth. 14Therefore hath the LORD watched upon the evil, and brought it upon us: for the LORD our God is righteous in all his works which he doeth: for we obeyed not his voice."
(from Daniel chapter 9)"
