Juggling With Eggs‘The [#NATO ]Treaty committed each member to share the risk, responsibilities and benefits of collective defence – a concept at the very heart of the Alliance.
In 1949, the primary aim of the Treaty was to create a pact of mutual assistance to counter the risk that the USSR would seek to extend its control of Eastern Europe to other parts of the continent. The Treaty also required members not to enter into any international commitments that conflicted with the Treaty.’
