Why Are World Leaders Shunning Buhari?

TRACKING____While others might not be overly worried about the world leaders’ summit that took place in Seoul, South Korea, a few percentage of Nigerians have expressed concern about the absence of President Muhammadu Buhari.
What seems to be even more worrisome, is the fact that both former Presidents Good luck Jonathan and Olusegun Obasanjo were invited to participate in the World Summit.One cannot help but wonder what reasons are there for excluding the Nigerian President or why they would rather have the former presidents. Something is definitely amiss!Meanwhile Dr Goodluck Jonathan took the time to express his delight when he shared a group picture of himself, alongside his wife, Patience, and also former president Olusegun Obasanjo.Are world powers sending a message about President Buhari’s administration?
Is something really going on that we do not know about or ought to know?
