Keynes In The Clouds

Ch 24 IV The General Theory
But if nations can learn to provide themselves with full employment by their domestic policy...there need be no important economic forces calculated to set the interest of one country against that of its neighbours. There would still be room for the international division of labour and for international lending in appropriate conditions. But there would no longer be a pressing motive why one country need force its wares on another or repulse the offerings of its neighbour...with the express object of upsetting the equilibrium of payments so as to develop a balance of trade in its own favour. International trade would cease to be what it is, namely, a desperate expedient to maintain employment at home by forcing sales on foreign markets and restricting purchases, which, if successful, will merely shift the problem of unemployment to the neighbor which is worsted in the struggle, but a willing and unimpeded exchange of goods and services in conditions of mutual advantage.
