(4) The expropriation of German private property is not limited, however, to the ex-German colonies and Alsace-Lorraine. The treatment of such property forms, indeed, a very significant and material section of the Treaty, which has not received as much attention as it merits, although it was the subject of exceptionally violent objection on the part of the German delegates at Versailles. So far as I know, there is no precedent in any peace treaty of recent history for the treatment of private property set forth below, and the German representatives urged that the precedent now established strikes a dangerous and immoral blow at the security of private property everywhere. This is an exaggeration, and the sharp distinction, approved by custom and convention during the past two centuries, between the property and rights of a State and the property and rights of its nationals is an artificial one, which is being rapidly put out of date by many other influences than the Peace Treaty, and is inappropriate to modern socialistic conceptions of the relations between the State and its citizens. It is true, however, that the Treaty strikes a destructive blow at a conception which lies at the root of much of so-called international law, as this has been expounded hitherto. The principal provisions relating to the expropriation of German private property situated outside the frontiers of Germany, as these are now determined, are overlapping in their incidence, and the more drastic would seem in some cases to render the others unnecessary. Generally speaking, however, the more drastic and extensive provisions are not so precisely framed as those of more particular and limited application. They are as follows:-- (_a_) The Allies "reserve the right to retain and liquidate all property, rights and interests belonging at the date of the coming into force of the present Treaty to German nationals, or companies controlled by them, within their territories, colonies, possessions and protectorates, including territories ceded to them by the present Treaty."[21]
