The power function of president of USA& French

The executive power is vested in a President of the United States of America. 

Of all the Presidents in the Constitution, the one with the executive power is this President of the United States of America.   The President of the United States has legislative duties described in Article I Section 7 Clause 2.  George Washington joined the two Offices by hiding his ineligibility to the Office of President, which has remained vacant.

The President of the United States of America is most visible when representing the 50 States and the United States in foreign affairs and as the plaintiff in all litigation brought for and against the United States of America.  As the entity that owns the territory and other property belonging to the United States of America, the Confederacy is represented by the President of the United States of America.

Why does the President of the United States of America represent the United States of America?   The United States of America is represented by a Senate of a hundred members, far too large a number to stand in for the United States of America.  As the authorized holder of the executive power, the President of the United States of America is particularly suited to stand in for the United States of America.

Federal law is enacted by the Congress of the United States and the President of the United States to “preserve, protect and defend” the territory and other property owned by and ceded to the United States of America.  The President of the United States of America is a

proper representative of that Confederacy

Powers of French President:-

Unlike many other European presidents, the office of the French President is quite a powerful one, especially in matters of foreign policy, although it is the prime minister and his government that are formally expected to run the country. 

The president names the prime minister. However, since the French National Assembly has the power to dismiss the Prime Minister's government, the president is forced to name a prime minister that is agreeable to the majority of this assembly; this leads to political cohabitation.

When the majority of the Assembly sides with him, the President takes a more active role and may, in effect, direct the country's policy. The prime minister is then often a mere "fuse" — replaced when the administration becomes too unpopular.
