An American leader would be derelict of duty if he did not seek to understand all his options in such unprecedented circumstances. Presidents Lincoln during the Civil War and Roosevelt in the lead-up to World War II sought legal advice about the outer bounds of their power - even if they did not always use it.

I think it can be very important for the president to seek congressional approval for war , even though not constitutionally required to do so, in certain situations.

Without territory, it does not even have the resources to provide detention facilities for prisoners, even if it were interested in holding captured POWs.
