Yes, BH claimed the reason why "Western" schools are being attacked is because madrassas were attacked by security services (that sounds plausible).

Let's take a step back and look at the bigger picture - how does this thing end?
Plausible scenarios:

1. Insurgency runs out of steam. Northerners realise that they want a future for their children more than they want to give the police a black eye. BH is run out of town. Jonathan consolidates his position.

2. BH succeeds, aggravates the rift that already exists between Christian and Muslim in Nigeria. Northern Christians call up on Christians in the South to rise to their defence. Polarisation intensifies, hostilities commence. Nigeria ceases to exist as a united entity.

Given the ineptitude of the Nigerian security services these are the two most possible scenarios. Which one do you think is likely to occur?
