Moscow's war has caused major damage to Ukraine. Russia has not only usurped the territory of Crimea but also many enterprises, goods in storage, cash, and other bank assets. In eastern Ukraine, Russian troops have devastated buildings, factories, and bridges. The war has cost Ukraine at least 7 percent of GDP in lost production, and foreign investors have been scared off. Russia has also pursued a trade war against Ukraine, eliminating 18 percent of the country's prior exports. Ukraine has no reason to pay such an aggressor; in fact, Russia ought to pay reparations to Ukraine.
