Are Deserts Always on the Western Side of Countries?

No. Desert distribution depends on global atmospheric circulation, rain shadows, ocean currents, and continentality—not political borders. Major deserts occur on western coasts (Atacama, Namib, Sonoran) due to cold currents and subtropical highs, but also in continental interiors (Gobi, Sahara, Australian Desert) and polar regions (Antarctica). The premise confuses a common pattern with a universal rule.
