The UN countries form the backbone of the international economy. Developments in the global economy and geopolitics directly affect the Greek political-economic scene. Therefore, in various parts of this work, essential issues of the international economy and global geopolitics are explored, which largely determine the trends and prospects of our national economy. The military conflict between Russia and Ukraine-NATO, the powerful geopolitical coalition of BRICS, the international movement of capital for direct investments, the triggering of inflation in the international economy, the change in interest rates by the American Fed and the European Central Bank, fluctuations in energy resource prices, the enormous size of global public debt, etc., constitute factors that directly or indirectly influence the developments of the Greek economy. In the last section of the book, groundbreaking proposals and effective economic policy measures are proposed to achieve significant developmental performance, the rehabilitation of Public Finances, and the achievement of the primary goal of the sustainability of Greece's public debt.
