Watching the political events of late, there seems to be a brewing confrontation between the northern backed government of president Umaru Musa Yar'adua with what he sees as his southern political adversaries.
This all started with the protest by south-south governors threatening to pull out of the controversial "amnesty for militants" citing the alleged anti-south south stance by the federal government on the Petroleum bill and the relocation of  the petroleum university from PTI Effurun to kaduna.
From all indications, president Umaru Musa Yar,adua has hit back by directing the aggrieved governors to take their case to the federal house of assembly.
He has also chosen this period to pick on a fight with Lagos State Government over the prolonged issue on the creation of 37 Local Government Development Areas (LCDA) in the state. 
   Yar,adua seems to have upgraded the his alleged anti south-south stance to an anti-south. Gov Fashola of lagos state have questioned the president's motives having not shown any condolences to the people of Lagos state after the Atlas Cove debacle.

   Many have come to view the stance of this government as anti-south and at this point there seem to be a potentially huge confrontation between the federal government and  his southern counterparts.
