The Treaty of Tordesillas shows governments dividing incompletely surveyed territory on paper. Because the line was not established with adequate geographic knowledge, Portugal gained the part of South America that became Brazil. The result left the continent's largest country speaking Portuguese rather than Spanish. A comparable space treaty might reduce one category of conflict while embedding errors or ambiguities that become visible only after exploration. Accurate surveys and enforceable definitions are therefore part of the logistics of expansion.
