Self-Defeating Resource-Drain Strategy / 疲敌反强敌
Self-defeating resource-drain strategy / 疲敌反强敌 is the pattern 《资治通鉴·秦纪》104｜阴谋失算让秦国版图又又又膨胀了 extracts from 韩国’s attempt to exhaust 秦国 through the 郑国渠. Han’s plan is rational in the short term: make Qin commit labor, money, and years to an enormous project instead of attacking east.
The backfire comes from the project’s real usefulness. Because 吕不韦 already wants Guanzhong irrigation and because 郑国’s engineering plan can actually increase Qin’s grain base, the cost is not pure waste. Once the sunk cost is near completion, abandoning the project would hurt Qin more than finishing it, so the attempted delay becomes long-term Qin state capacity.

《资治通鉴·秦纪》110-2｜秦始皇的CP为何被驱逐出国 extends that residue into the next policy turn: the spy case becomes a sweeping anti-guest order, and Li Si’s answer reframes outside resources and outside talent as the very inputs that have made Qin stronger.
Key Claims
- A drain strategy can fail when the imposed burden is also durable infrastructure.
- The weaker state’s time-buying goal can conflict with the stronger state’s long-term capacity-building goal.
- Exposure does not automatically end the plan if the material project has become valuable enough to finish.
- The pattern is close to 阴谋阳谋转换 because the hidden motive and open utility of the same act diverge.
- Even when the target benefits materially, the revealed hostile motive can produce later security backlash against similar outsiders.
