Ian Bremmer shares his perspective on global politics this week:

What do we know about the assassination of Haiti's president?

Well, we know it's not making an awful lot of news the assassination of the leader of a country, because Haiti's a tiny economy. It's incredibly poor, it's been devastated by natural disasters and also by general lawlessness in the country. And over the last month, gang violence has become historically unprecedented. The police have been unable to maintain law and order in the streets, in most of the cities or sort of, major towns in Haiti. You've had thousands of Haitians displaced. You've had dozens of civilians killed and then overnight a gang entered the personal residence of the president. Again, police and presidential guard unable to stop them and he's dead. And his wife, the First Lady is in the hospital. It's a pretty staggering situation and obviously, some international support, some peacekeepers could be useful on the ground. Aid by itself is not going to do it right now.
