The quote reflects Belgium’s historical role as a battleground, emphasizing its readiness to sacrifice its land for the conflicts of larger powers. By mentioning "battlefield-ready lowlands," the author illustrates how Belgium has often been caught in the crossfire of European wars, becoming a canvas for the ambitions of stronger nations. The imagery of boots, hooves, and iron wheels evokes the mechanization of warfare and the inevitability of conflict that Belgium seems to endure.
Pynchon critiques the lack of foresight among European leaders, who view the future merely as administrative concerns rather than as a tapestry of human consequences. The phrase "exercise for clerks" suggests a disconnection from the real impacts of war, as decisions are made from behind desks without consideration for the lives affected. Overall, the passage conveys a somber reflection on Belgium's position and the broader implications of European conflicts.
