Could job rotation for world leaders work?

Ever wondered how Africa would look if we would introduce job-rotation among world-leaders? So we would have Obama/Trump deal with the security challenges, tribalism and nepotism Uhuru Kenyatta is dealing with?

We would have Uhuru Kenyatta be chairman of the European Union, Angela Merkel would be president of Tanzania etc. Interesting… Would they do a good job, each of them? I wonder. And… who would do better? So-called Western leaders in Third World Countries or so called Third World Leaders in Western countries?
