Besides his preference for a cohesive British Empire and a protective tariff, he felt an independent British defence programme would be the wisest policy. However, budget pressures and a strong popular pacifist sentiment, forced a reduction in the military and naval budgets. MacDonald involved himself heavily in foreign policy. Assisted by the National Liberal leader and Foreign Secretary John Simon, he continued to lead British delegations to international conferences, including the Geneva Disarmament Conference and the Lausanne Conference in 1932, and the Stresa Conference in 1935. He went to Rome in March 1933 to facilitate Nazi Germany's return to the concert of European powers and to continue the policy of appeasement. On 16 August 1932 he granted the Communal Award upon India, partitioning it into separate electorates for Hindus, Muslims, Sikhs and Untouchables. Most important of all, he presided at the world economic conference in London in June 1933. Nearly every nation was represented, but no agreement was possible. The American president torpedoed the conference with a bombshell message that the US would not stabilise the depreciating dollar. The failure marked the end of international economic co-operation for another decade.
