The policy is known as 'appeasement' and chiefly refers to the idea that, if you give competitive nations what they want, these belligerent nations will eventually reach a point where they are contented and will begin to support and collude with the rest of the international community.
Explanation:
Appeasement in an international context is a diplomatic policy of making political or material concessions to an aggressive power in order to avoid conflict. the policy of delivering concessions to the absolute powers in order to evade opposition-governed Anglo-French foreign policy through the 1930s. It became indelibly associated with Conservative Prime Minister Neville Chamberlain.
