What country does NOT have land with elevations 1000ft?

There are, in fact, a number of countries whose highest points are less than 1000 ft below sea level. The lowest is the Indian Ocean archipelago of the Maldives, its highest point only 7 ft above sea level, and potentially at risk of total submerging due to rising sea levels. Also with high points lower than 1000 feet are (from lowest to highest): Tuvalu, Marshall Islands, the Gambia, the Bahamas, Nauru, Vatican City, Kiribati, Qatar, Bahrain, Monaco, Singapore, Denmark, Palau, Malta, Lithuania, and Guinea-Bissau. Most of these countries are flat island nations, and the remainder are flat coastal areas with evidently few hills or mountainous regions, or micro-nations so small that a sizeable hill simply would not fit in the country's borders.
