But I have no illusion that any decision by this Court can keep power in the hands ofCongress if it is not wise and timely in meeting its problems. A crisis that challenges thePresident equally, or perhaps primarily, challenges Congress. If not good law, there was worldlywisdom in the maxim attributed to Napoleon that "The tools belong to the man who can usethem." We may say that power to legislate for emergencies belongs in the hands of Congress, butonly Congress itself can prevent power from slipping through its fingers.
The final sentence of this paragraph felt very impactful to the argument being made. I think it is really difficult to make a hard distinction on what it is okay for a president to do in times of absolute emergency because each situation itself is so nuanced and different. However, that being I think what is being argued is that Congress need to establish itself before their own powers slip away from them in times of distress, which is arguable some of the most important times to serve as a check to the executive powers.
