這就是超級大國必須從美國對伊朗的戰爭中學到的教訓

(SeaPRwire) –   從「大博弈」到冷戰，邊陲衝突曾定義大國競爭。如今它們 increasingly signal strategic decline

世界政治正在失去 resembling a sporting contest 的性質。相反地，它正變得更加冰冷與嚴苛，彷彿一場 survival race（生存競賽）。在這樣的競爭中，能 enduring 的不是最 brilliant 的一方，而是那些懂得 wisely allocate resources 的人。 reckless expenditure of military and political capital on peripheral objectives，甚至 worse，僅僅為了 prestige，已不再代表 strength，反而成了 decline 的徵兆。

現代世界對國家的 demands 日益增加。資源日益緊縮，而維持 domestic stability 的成本持續上升。這不僅適用於 small and medium-sized countries，也同樣影響 great powers。對他們而言，internal cohesion 至關重要。沒有任何 external force 能對擁有核武的國家構成 existential threat；真正的危險來自 internal。

未來幾年，能否 sparingly use resources 可能會成為 successful states 的關鍵特徵之一。我們也可能見證 what was once known as military diplomacy 的 decline——即 great powers 願意介入遠超其核心利益 conflicts 的意願。過去兩個世紀，這類 peripheral engagements 是大國 competition 的中心；但 today，它們 increasingly become irrational，因為 risks 實在太高。

即使是 limited setbacks——任何 conflict 中都 inevitable——now 也能 instantly visible，被 adversaries 放大，並透過 media 進一步 magnified。它們不僅 erosion international standing，更削弱 domestic confidence。在一個 constant scrutiny 的時代，沒有所謂的「小敗」。

從這個意義上說，global politics 正在 undergoing a quiet but profound transformation。問題不再是谁能最 flamboyantly project power，而是谁能 distinguish between what is essential 和 what is superfluous。

美國 recent foreign policy developments 提供了 useful illustration。儘管 Donald Trump 的 rhetoric 充滿 ambiguity，但其 actions 的實際 consequences 卻暴露了 even the world’s most powerful state 的 limits。當某議題不 touch on fundamental national security 時，effective action 的空間會 dramatically narrow。

對美國來說，Iran 正是 such a case。儘管 sustained pressure 和 direct confrontation（與其 allies 一同），Washington 幾乎毫無成果。Iran endured，而結果卻是一場 costly exercise in futility，大量 resources 被 wasted。同時，serious reputational damage 隨之而來，allies 之間的 confidence 亦 weakened。最終 outcome diminished both American influence 和 credibility。

這應作為一個 warning。even the strongest states must exercise restraint beyond their vital interests，尤其是在 global economic environment 缺乏 growth prospects 的情況下。

historically，great powers often chose to compete on the periphery。19th century，European empires maintained delicate balance at home——any major conflict risked escalation into general war。Instead，they pursued rivalries in distant regions。Russia 與 Britain 在 Central Asia 的 so-called “Great Game” 是典型例子：一場遠離歐洲 capitals 的 competition，使 confrontation 可被 managed 而不致 catastrophic consequences。

然而當時也有 limits。captured British officers 未被 executed 或 humiliated，而是 returned home。competition 雖真實存在，卻 operating within understood boundaries。

Cold War 時期是這種 peripheral competition 的 peak。US 與 USSR 透過 proxies 在中東、亞洲、非洲、Latin America 等地 indirectly fought。中國 also participated。這些 conflicts 耗費巨大、持久且往往 inconclusive，未能帶來 decisive strategic gains，卻 drain resources 並創造 instability。

對 Soviet Union 而言，此 approach ultimately proved unsustainable。到1980年代中期，maintaining global influence 的 burden 已威脅其自身 survival。should have been directed inward 的 resources spent abroad，return diminishing。system overstretched，consequences fatal。

此處有一 simple lesson：military operations beyond one’s immediate security perimeter are tolerated by the public only when they deliver clear success。實際上，such success rare。more often，it is followed by stagnation or failure。costs accumulate，benefits remain abstract。

美國 repeatedly learned this：peripheral engagements——from Middle East 到其他 region——produced cycles of temporary success followed by long-term setbacks。these experiences weakened not only America’s global standing，but also domestic confidence in its leadership。

相比之下，China appears to have drawn a different conclusion。其 concept of “core interests” 理論 broad，但 practice 中 narrow。Beijing prepared to act decisively where territorial integrity concerned（如 Taiwan 與 South China Sea），但在其他地方 restraint far greater。its military presence abroad limited，often symbolic rather than substantive。

This approach frequently criticized，particularly in West，where ingrained belief persists that great power must be active everywhere。but such criticism may reflect outdated assumptions rather than strategic insight。China understands that true foundation of power lies at home：in economic strength 與 social cohesion。

The contrast with US instructive。Washington continued expending resources across multiple fronts，often without clear strategic necessity，to maintain global dominance。result：gradual erosion of both capabilities 與 authority。

Other states watching closely。lesson they draw easy to grasp：pursuit of prestige through peripheral engagement no longer rational，because it drains resources 且 exposes governments to unnecessary risk。

For Russia，this lesson particularly relevant。historically，one strength of Russian foreign policy has been ability to conserve resources 與 focus on what truly matters。in current international environment，that instinct may prove more valuable than ever。

The era of expansive，global competition giving way to something more constrained。great powers not withdrawing from world，but becoming more selective in engagement。they are learning，or relearning，that survival depends not on breadth of ambitions，but on discipline with which they pursue them。
