How to quash a Presidential rebellion?

I had this thought the other day (just hypothetical): Let us suppose the US Supreme Court issued an order to the US President and that President refused to comply. If egregious enough, Congress could impeach and convict the President. Let us suppose, upon conviction, the President refused to leave Office. Let us, further, suppose the entire Executive branch staff (Secret Service, Justice Department, etc.) "fell in line" behind the President and moved to keep the President in Office. In short, in this scenario, the Courts and Legislature are attempting to enforce the Constitutional Law, but the Executive branch has "rebelled". What guarantee exists to make sure the President complies? Who could force the President to leave? What's more, how could that person/people do so?

You have the wrong end of the stick.

The Supreme Court has no authority (Other than writs of Habeus Corpus, or of Mandamus) to 'order' the President to do anything.

What would happen if the President ignored a ruling of the Supreme Court?

Ask the Cherokee's.

When the Supreme Court ruled that the forced removal onto the "Trail of Tears" to Oklahoma of the Cherokee from Georgia and surrounding areas was illegal, the President (Andrew Jackson, the founder of today's Democratic Party) simply said "Justice Marshall has issued his ruling. Now let us see how he plans to enforce it.", and sent Federal Troops to round up the Cherokee and drive them from their homes.

life is a zit getting ready to pop

Ask the UN to intervene?

theres about 300 million people in the country and that's a lot of people

if we keep the federal government small and limited the executive branch should not have enough power to supress 300 million people

I find the notion of the Courts and Legislature "attempting to enforce the Constitutional Law" rather unlikely, at this point. As was mentioned above, the people would ultimately decide.

separation of powers. President cannot be given orders by the supreme court. As president He is immune from court actions for any acts committed as president. If congress impeaches and the senate removes him. He has no choice
he is no longer president and can be forcefully removed. If the presidential staff attempted to keep the president in there . They are guilty of treason and would be arrested by the new president and his staff
