My Administration has initiated many new approaches to cope with these pressures. We started a multi-year budget system, and we began a system for controlling Federal credit programs. Yet in spite of increasing needs to limit spending growth, we have consistently adhered to these strong budget principles: • Our Nation's armed forces must always stand sufficiently strong to deter aggression and to assure our security. • An effective national energy plan is essential to increase domestic production of oil and gas, to encourage conservation of our scarce energy resources, to stimulate conversion to more abundant fuels, and to reduce our trade deficit. • The essential human needs for our citizens must be given the highest priority. • The Federal Government must lead the way in investment in the Nation's technological future. • The Federal Government has an obligation to nurture and protect our environment-the common resource, birthright, and sustenance of the American people.
