Another advantage that would follow such a process is that it would facilitate the transition to a republic in Canada, Australia and New Zealand. While some distance may be remote, such a transition is ultimately inevitable, although it may be difficult to achieve in Canada, where a constitutional amendment changing the Crown`s position would require unanimous agreement between the federal government and the provinces, which would be very difficult to achieve. Moreover, an attempt at an electoral system for the office of Governor General would require a prime minister who is a strong supporter of a republic, and such prime ministers are hard to come by. For non-executive heads of state, there is often some degree of censorship on the part of the politically responsible government (such as the head of government). This means that the government quietly approves the agenda and speeches, especially when the Constitution (or customary law) assumes any political responsibility by granting the Crown inviolability (in fact also political pruning), as in the Kingdom of Belgium from the beginning; in a monarchy, this can even be extended to some extent to other members of the dynasty, especially to the heir to the throne. Most executive agreements were made on the basis of a treaty or an act of Congress. However, presidents have sometimes entered into executive agreements to achieve goals that would not have the support of two-thirds of the Senate. For example, President Franklin D acted. Roosevelt, after the outbreak of World War II, but before the United States entered the conflict, an executive agreement that gave the United Kingdom 50 overflow destroyers in exchange for 99 years of leases from some British naval bases in the Atlantic. The use of executive contracts increased significantly after 1939. Before 1940, the U.S.
Senate had ratified 800 treaties and presidents had concluded 1200 executive agreements; From 1940 to 1989, during World War II and the Cold War, presidents signed nearly 800 treaties, but negotiated more than 13,000 executive agreements. .
