 of the Royal Prerogative is determined by Parliamentary voting to fund the powers being exercised. The restraining conventions when exercising Royal Prerogative Powers is increased by the fact that the Ministers of the Crown are accountable to the Parliament. Such an approach to accountability indicates the control of the Parliament over the Crown and Executive.
In order to determine whether a convention that restrains the Royal Prerogative to go to war exists or not, it is essential to have a comprehensive overview of the context of war in relation to foreign affairs. Foreign affairs are a differentiated field of execution action that is not easy to control and scrutinize using the available legal and non-legal frameworks. In the context of the United States, it is arguably evident that Congress has the power to exercise any form of control on the presidential decisions and actions when going to war. This implies that restraining the powers of the Prerogative is only attainable using the available constitutional conventions. This is because there is no any other practical mechanism that can be used in controlling actions undertaken by the executive except through the use of constitutional conventions.
In conclusion, it is arguably evident that there are no other feasible legal and non-legal frameworks that can be used to limit the executive use of Royal Prerogative except for parliamentary controls because foreign affairs and war declarations are matters that cannot be decided upon by the electorate. The aspect of personal accountability of the members of Executive serves to impose significant constraints regarding the exercising of the Royal Prerogative.
