So, there I am, sitting in the cab of my ambulance, debating the rights and wrongs of the budget for Yo Blair's grand warmongering schemes; I'm wondering whether we should be providing armour-plated landrovers, and flak jackets for "our boys", or spending it on the NHS. I'm also wondering it against the background of my son, whose regiment is currently squaring up either for its third tour in Basra, or its first in Afghanistan. "In no more than 500 words, discuss."
