What Is the Strategy, Strategic Thinking on the Allies?

In Gallipoli, the fact that you saw thousands of troops dying to machine gun and artillery was in a sense normalized by what had already happened on the Western Front. But there's another thing which is it was the irony of the British War on the Ottoman Front that the more they failed, the deeper they were drawn in. They could not hand a weaker enemy like the Ottomans of victory without it undermining war morale or indeed enhancing the position of Germany and its allies. The people that responded most directly to the threat of jihad were actually British war planners for whom this played on their thinking right through the war.
