Yesterday, Kenya concluded its national mourning for 147 people who were massacred Thursday at Garissa University. Just four al Shabaab terrorists held the campus for 15 hours before trained commandos finally arrived and killed them all in just 15 minutes. The terrorists singled out Christians, but religion is only part of the story. Kenya is East Africa's economic leader, with a vast international presence: the US military, multinational companies, tourists and NGO's. It also has one of the world's most corrupt governments -- breeding terror and responding with crackdowns that reinforce corruption and create more violence. Last week's attack was the latest wake-up call with global implications.
