Final answer:
The President can federalize the National Guard to restore order during the protests in Washington DC and use the bully pulpit to address the nation for calm. Cooperation with other branches of government is crucial for effective and proportionate response.
Step-by-step explanation:
In the given scenario where rioters are protesting against the War in Iraq and tensions are rising to the point of violence in Washington DC, the President, acting as the Commander in Chief, has several options to manage the situation. The President could choose to federalize the National Guard, which is within his powers during times of national emergency or unrest. The National Guard can assist local law enforcement in restoring order and ensuring the safety of citizens. It's essential for the President to communicate effectively with the public and law enforcement to defuse the situation and prevent further violence. Additionally, the President can utilize the power of the presidential bully pulpit to address the nation, calming fears and calling for peace.
To ensure that the use of military powers is proportionate and justified, it might be necessary for the President to work hand in hand with other branches of government to negotiate and discuss a suitable response, involving persuasion and compromise. This approach should focus on both immediate action and long-term solutions, thereby catering to the public's demand and addressing the root causes of the protest.
