Well, we've had a strong military component now for many years in that region of the world, and it has really seemingly only exacerbated the problems. Does Iraq need a solid national non-sectarian army? Absolutely. It's a pity that after all these years, there was a failure to create such an army, as some of the other witnesses have explained.
In the long term, western military involvement is only going to be a small part of the solution. We need to create strong national institutions in Iraq and somehow in neighbouring Syria as well, but beyond that, we need to invest much more in aid and reconstruction in creating the institutions and political spaces that will move those societies away from sectarian violence.
