Problem: Royal assent:

In Commonwealth realms other than the UK, royal assent is granted or withheld either by the realm's sovereign or, more frequently, by the representative of the sovereign, the governor-general. In federated realms, assent in each state, province, or territory is granted or withheld by the representatives of the sovereign. In Australia, this is the governors of the states, administrators of the territories, or the governor-general in the Australian Capital Territory. For Canada, this is the lieutenant governors of the provinces. A lieutenant governor may defer assent to the governor general, and the governor general may defer assent to federal bills to the sovereign.

In Commonwealth realms, who is the representative of the sovereign?
---
A: the governor-general


Problem: Separation of powers under the United States Constitution:

The president is the civilian Commander in Chief of the Army and Navy of the United States. He has the authority to command them to take appropriate military action in the event of a sudden crisis. However, only the Congress is explicitly granted the power to declare war per se, as well as to raise, fund and maintain the armed forces. Congress also has the duty and authority to prescribe the laws and regulations under which the armed forces operate, such as the Uniform Code of Military Justice, and requires that all Generals and Admirals appointed by the president be confirmed by a majority vote of the Senate before they can assume their office.

Who has the power to declare ware?

A: Congress
