I cannot, therefore, reconcile it to my sense of duty to embark in a scheme for new modelling the position of the Greek population in those countries at the hazard of all the destructive confusion and disunion which such an attempt may lead to, not only within Turkey but in Europe. I am by no means persuaded, were the Turks even miraculously to be withdrawn (what it would cost of blood and suffering forcibly to expel them I now dismiss from my calculations) that the Greek population, as it now subsists or is likely to subsist for a course of years, could frame from their own materials a system of government less defective either in its external or internal character, and especially as the question regards Russia, than that which at present unfortunately exists. I cannot, therefore, be tempted, nor even called upon in moral duty under loose notions of humanity and amendment, to forget the obligations of existing Treaties, to endanger the frame of long established relations, and to aid the insurrectionary efforts now in progress in Greece, upon the chance that it may, through war, mould itself into some scheme of government, but at the certainty that it must in the meantime, open a field for every ardent adventurer and political fanatic in Europe to hazard not only his own fortune, but what is our province more anxiously to watch over, the fortune and destiny of that system to the conservation of which our latest solemn transactions with our Allies have bound us.

These arguments about natural defences and strategic boundaries are pushed too far. Real defence and security comes from the guarantee which is given by the fact that they cannot touch you without declaring war on all those interested in maintaining things as they are.
