In 1990, in a letter to the UN Secretary-General, Kuwait mentioned violations “of all international laws” by Iraq:
We wish to draw attention to a phenomenon which has no precedent in history, namely, the Iraqi occupation authorities’ organized operation for the purpose of looting and plundering Kuwait. It is impossible to compare this operation to any similar incidents or to provide an exact account thereof because it is in effect an operation designed to achieve nothing less than the complete removal of all Kuwait’s assets, including property belonging to the State, to public and private institutions and to individuals, as well as the contents of houses, factories, stores, hospitals, academic institutions and to universities.
