We all know that notable politicians are behind Boko haram. It is more political than religious. GEJ's political opponents are working day and Night to frustrate any positive effort that he is trying to make by funding and unleashing terror on helpless Nigerian masses.
I feel that if GEJ puts forward a proposal for the division of Nigeria into different countries on a North/South basis, these politicians will get scared and cease their nefarious activities. They stand to lose. I don't want to call names, but it is well known that these politicians own oil wells and other economic interests in the southern part of Nigeria. They will poo in their pants if they hear anything that sounds like division.
Moreover, the grieving politicians that lost the last elections and are among those sponsoring Boko Haram will become frightened because their aim is to rule an oil rich Nigeria and not an agrarian rich but economically poor North.
I think he should come out and propose a sovereign national conference where the intention of division will be clearly spelt out. Then, he should secretly call these men and tell them that if he hears any shot from a catapult from Bokoharam, they will lose everything, starting with a radical probe of their stolen oil wealth, seizure of all their wealth that they cannot account for and a subsequent division of Nigeria. If these men don't cease, he can then ensure the complete implementation of his threat. For all I care, we are either brothers or enemies.
Believe me, Boko Haram will disappear this way. Military action will not solve the problem.

That is the wisest thing to do, but the idiot will never do it

If Nigeria is too big and complex for his fish-brain, he should declare himself incompetent. Contesting against Sylva in Bayelsa is not a bad idea.

They will assassinate him if they 'think' he will propose such. Such proposal are better made by his spokesman man 'Abati', who should then be fired for 'misrepresenting' the president. NIgerians and political commentators will subsequently have a field day discussing the issue.

This exactly what Dora Akunyili did for GEJ during the Yar Adua illness saga. And many Nigerians are proud of her for that.
