will spread over Germany, reach Belgium, and finally sweep England into its vortex. Should our efforts for peace succeed, Europe may begin a new career with more or less of hope and of concord; should they fail, we must keep our sword in the scabbard as long as we can, but we cannot hope to be neutral in a great European war. England cannot be indifferent to the supremacy of France over Germany and Italy, or to the advance of Russian armies to Constantinople; still less to the incorporation of Belgium with a new French Empire.' [Sidenote: OUR POLICY ABROAD] As usual, Lord Palmerston had his own ideas and the courage of them. Within three weeks of the Russell Memorandum to the Cabinet he accordingly stood out in his true colours as a frank opportunist. The guiding rule of his foreign policy, he stated, was to promote and advance, as far as lay in his power, the interests of the country as opportunity served and as necessity arose. 'We have no everlasting union with this or that country--no identification of policy with another. We have no natural enemies--no perpetual friends. When we find a Power pursuing that course of policy which we wish also to promote, for the time that Power becomes our ally; and when we find a country whose interests are at variance with our own, we are involved for a time with the Government of that country. We find no fault with other nations for pursuing their interests; and they ought not to find fault with us, if, in pursuing our interests, our course may be different from theirs.'
