who said balance of power is basic principle of international relations
Balance of power (international relations) The principle involved in preserving the balance of power as a conscious goal of foreign policy, as David Hume pointed out in his Essay on the Balance of Power, is as old as history, and was used by Greeks such as Thucydides both as political theorists and as practical statesmen.[6]
Powers of the President of the United States The Separation of Powers devised by the founding fathers was designed to do one primary thing: to prevent the majority from ruling with an iron fist. Based on their experience, the framers shied away from giving any branch of the new government too much power. The separation of powers provides a system of shared power known as "checks and balances". For example, the President appoints judges and departmental secretaries, but these appointments must be approved by the Senate. The president can veto bills, or deny them. If he does that, the bill is sent back to Congress.
