Answer:
I'm not sure if this is a subjective or objective question, but my answer would be the president's ability to command the US army
Step-by-step explanation:
it's a huge responsibility. you think being the leader of the whole country is a big job? imagine having the power to start a war over anything. oil prices too high? war. another leader of a country said something and it made you mad? war. being the commander-in-chief is also an important responsibility when the war is being started by another country.
what happens if France and Japan are fighting? Do you decide to intervene and go to war, possibly destroying the economy and deploying thousands of men and women? what happens if the country is bombed? or do you keep yourself out of the situation, possibly ruining the trust between yourself and your allies across the world?
Who knows? I know I'd never want to deal with that.
