Chamberlain did not try to get rid of Eden and Cranborne, but he felt a great sense of relief at their going. Now that they had gone, the Foreign Office could be run as he wanted it run, secure in the knowledge that Halifax and Butler were enthusiastic proponents of his own point of view who would be less sensitive to Opposition opinion and more willing to take the steps needed ‘to avoid another Great War’. In particular they would help him to rid himself of ‘Collective Security’ of which Eden had been the symbol and Chamberlain's attack on which was thought of by those who heard it in the House of Commons to be ‘a scrapping of the ideas which had been built up since the war’ and a reversion to ‘good old Tory doctrines’.

In this, those who heard him were mistaken. In preferring ‘national strength’ to an ‘international police force’ (which previously he had wanted) Chamberlain took a politician's view of Tory opinion.
