El Salvador used to be murder capitol of the world. Now it's the 2nd to safest country in the Western Hemisphere. How did President Nayib Bukele do it? He cracked down on crime and jailed more than 65,000 gang members. El Salvador now has the world's highest incarceration rate by far and a national homicide rate that's down by 92%. His approval rating now stands at 90%. The Bukele Model can and should be replicated everywhere. It works.
