You might be talking about the speech made by the Egyptian
President Gamal Nasser regarding the nationalization of the Suez Canal, a
waterway in Egypt financed by the British and the French. The waterway is a very
important sea route for the Brits and the French, and Nasser want more Egyptian
control. Nasser proceeded with the nationalization and sparked the Suez crisis.
John O'Sullivan coined the term "manifest destiny".
A treaty is an international law agreement signed between actors on the international law (mainly sovereign nations and international organizations).
When two countries sign a treaty, the execution of that is stated to be interpreted "in good faith" by the Vienna Convention.
However, if a modern treaty is signed between two countries and it is registered within the United Nation it is possible to appeal to the International Court of Justice, which is the judiciary organ of the United Nation.
