Why do the president, member of congress and fedral judges take an oath to defend the constiution of the united states?

aren't cheetos good enough to be president?

the factors that the economies of the muslim empires prosper were:

1- land trade routes-located between three continents  

2- sea trade routes

trade contributed to the spread of muslim empires, and with that islamic culture led to a growing feeling of internationalism resulted in the transfer of technology, science, and other cultural forms.
