How about adding a hefty tariff against all oil products sold outside this nation? The money earned should then be earmarked to debt reduction. No earmarks.
Who pays the tariff, the producer or buyer?
A market is a market. It makes no difference in a free market where the oil goes. That is, until economically ignorant busybodies start interfering with the market with ill-conceived tariffs, taxes and regulations which drive up the price even higher in the home country.
