That sounds ridiculous. Sir Richard should advice the whole British army to adopt Buddhism or way of Samurai if he wanted to convince our soldiers in some rubbish like that. But those statements signify grievous changes in British foreign policy. Otherwise there would be no need in such blatant propaganda of death.
I suspect that that’s because of our American friends who are starting new big stir about Kurd state founding. Of course they’ll draw fresh British forces into Turk or Syrian or (God forbid!) Iraqi territory. And near Iraq Iran has already begun to concentrate jahid sub-units.
So seemingly Sir Dannatt in such way wants to invigorate our soldiers in the face of Middle Eastern hell and to that “lingering fight against extremism” inside UK. Because there are about 2,000 terrorists preparing dozens of explosions on British territory. And MI5 and MI6 just seek for help among local Muslims (as if they would betray their congeners) and play games in I-net under pretence of fight against terrorism on extremist Islam sites.
Thus Chief of the General Staff meant not only British soldiers but common Britons too. According his advice all of us should prepare to life after death. And our authorities just dance to US tune. They would create course of jahids in London if Americans would demand that.
