Sixteen years or six?

Fellow Nigerians, the answer to this question could define our future under the present administration.
The slow pace of developments under president Buhari is no secret, he took six months to get his cabinet together and it has taken another four to sign this year's budget.


The patience of Nigerians have understandably worn thin and complaints have replaced optimism, why is it taking the government so long to deliver?
The president has all of four years to make good on his campaign promises and one year is yet to elapse so I don't have issues on that front but what I do have issues with is this, is the government working to right the wrongs of the past administration's six years in power or PDP's sixteen?
It has become common for party faithfuls to tell Nigerians it won't take them a day to fix the wrongs of PDP's sixteen years. Let's examine the time frame in question.
From 1999-2007 General Olusegun Obasanjo held sway, while he won't admit it in public, it is assumed he is an APC patron and worked against the second term ambitions of his former protege, Goodluck Jonathan. He served the first of those sixteen years. It is interesting to note that he has put up no protest against APC's assertion that he contributed to the depletion of our common wealth.
Late president Umaru Musa Yaradua served from 2007-2010, what his sins were, APC is yet to tell us but he's part of the magic number. 16 years.
Goodluck Jonathan had the Ill luck of serving out the last of those 16 years from 2010-2015. Ill luck because it seems he is being held accountable for the sins of his predecessors having been the most recent of the three.
The issue is this, if APC is cleaning up a sixteen-year rot, why is it focused on the events of six? I stand to be corrected but to my knowledge, no one has been questioned for the corrupt activities and mismanagement which APC infers took place under Obasanjo and Yaradua.
Dear APC, who is to be held responsible here, the 16-year-old teenager or the 6-year-old child?
