The sovereign is the ultimate authority. In the USA “we the people” delegate the sovereign power to our elected officials.
They are now exercising that power in the interest of the people (they believe) that grant that power.
You're not American so it might be hard to wrap your head around, but here the "sovereign" leadership is not the ultimate authority.
You don't actually believe in the core tenets of the USA if you think that the government should have or should exercise unchecked, abusive power.
