Amanullah, the new Amu' of Afghanistan, has begun his reign
badly by invading British territory. Last week Afghan troops crossed the ft ontier west of the Khyber Peas and occupied some bills near Landi Kotal. They were driven from these positions on Friday week. The statement that-aeroplanes were used to bomb the Afghans on the hills should remind nervous people that the Air Service and other military developments have simplified the question of frontier defence. The Afghans, having no aeroplanes of their own, are helpless when our airmen attack them, and the hillsides where. they naturally take cover make excellent targets. It is a pity that the Afghans, with whom we have been at peace for nearly forty years, should have broken out in this unneighbottrly fashion, presumably at the Instance of itinerant fanatics in Turkish pay. But their invasion tan have little military significance if, as appears to be the ease, the frontier authorities deal promptly with the aggressors.
