While the internal policy of the Republic was veiled in so much ideology and marred by tyrannous cupidity, its foreign policy was based on sound realism. The French plenipotentiaries, like Joseph II, but far more clearly, perceived that the possession of the key positions on the Scheldt and on the Meuse was essential to the security of the country and to its commercial prosperity. A comparison between the clauses of the treaty of The Hague and of the treaty of Muenster is particularly enlightening. Apparently, the demands of the French were moderate; in fact, they entirely reversed the situation created in the seventeenth century. No wholesale annexations would have given the French equivalent advantages. The choice of the Republic was dictated by sound strategic principles and determined by the same motives as had guided the Dutch in 1648. But the Belgian people, suffering from all the evils of foreign occupation, could derive but scant satisfaction from the restoration of the lost districts. The Convention was waging war on the world and bleeding Belgium white in order to find the necessary resources. The provinces were obliged to pay a contribution of 80,000,000 francs, amounting to six times the previous yearly budget. Hostages were taken from the towns which could not contribute their share. Requisitions of all raw material were systematically organized. Cambon boasted to the Convention that the Netherlands not only provided for the upkeep of the Republican armies, but also enriched the national treasury. Under the management of the "Agence de Commerce et d'Extraction de la Belgique," the treasuries of churches, convents, corporations and municipalities were carted away, together with pictures, works of art and industrial machines. The Republican agents, nicknamed the "French sponges," even went as far as plundering private property. At the same time, the value of the assignats had fallen to a ridiculously low level, and in order to check the corresponding rise in prices the authorities had fixed a "maximum" and obliged the traders to keep their shops open.
