无论美国总统特朗普在这场由他发动、如今却又选择退却的灾难性战争中，与伊朗达成何种协议并大肆宣扬，显而易见的是，在与其“让美国再次伟大”（MAGA）使命相关的地缘政治剧烈震荡中，他本人以及美国外交政策，才是最大的“伤亡”者。
如今正在浮现的，是一段迈向新世界秩序的过渡期，其核心元素如下，而这些元素也标志著美国例外主义与对全球体系霸权控制时代的终结。
1.多极权力架构
美国将不再是中东与亚太，全球两个竞争最激烈地区，唯一或主要的安全保障者。中国、俄罗斯与区域强权将透过竞争性联盟、临时协议与地方势力范围填补权力真空。二战后的“以规则为基础的秩序”，将让位于交易式、多重结盟的集团体系。
2.去美元化与平行金融体系
这场由美国与以色列联合进行、被包括美国最亲密盟友在内的大多数国家视为非法、危险并违反国际法的美以伊战争，加速推动各国以非美元货币进行贸易的结算。黄金、数码人民币，或新型储备货币组合的出现，进一步分裂全球金融体系，如今更为真实。
虽然美元作为全球主要货币的地位尚未崩溃，但其透过印钞与垄断全球储备货币地位而享有的“过度特权”，即低成本借贷能力流失，已成为这场战争最深远的后遗症之一。这将严重削弱美国金融实力，并导致美国金融资产贬值。
3.跨大西洋与亚洲联盟弱化
北约以及美国在亚洲的安全盟友（日本、台湾、韩国、澳洲），正逐渐与这个奉行“美国优先”、难以预测、且在未与盟友协商下发动单边战争的华盛顿保持距离。所有盟友如今都承受著油气价格飙升与供应链中断所带来的连带冲击。
部分欧洲国家正在推动更独立的防务与外交路线，而亚太国家则加深与中国的经济联系，以对冲美国政策波动所带来的风险。
4.非国家与区域行动者崛起
随著大国竞争使联合国功能陷入瘫痪，区域组织（非洲联盟、东盟、海湾国家合作委员会、欧亚经济联盟）正努力在安全、贸易与气候议题上争取更大权威与共识。与此同时，混合型行动者——私人保安公司、科技平台与财团，也正试图获取准外交权力。
5.主权与干预原则的转变
特朗普发动美伊战争，使“预防性战争”与单边干预主义失去正当性；而这些做法，原本一直是二战后西方外交政策与地缘政治的重要基石。如今，一种偏向主权、不干涉与有条件中立的新规范正在形成，这实际上也削弱了美国与西方式民主及“自由”输出的影响力。这也意味著，各国将拒绝扮演美国“副手”角色，以协助强化美国与西方霸权。
国际法的发展方向，也逐渐倾向非惩罚性调解，以促进和平，并防止或化解如伊朗案例般代价巨大的毁灭性战争——因为这类战争在人命、经济与国际声誉上的成本，早已超越任何战术收益。
6.能源与资源重新洗牌
一场绿色浪潮海啸正在形成。这已不只是气候变迁问题。霍尔木兹海峡的封锁，实际上终结了“能源安全选项”的时代，并使绿色转型成为全球经济的生存必要。
各国为减少对化石燃料战略瓶颈的依赖，将加速能源转型。而这场石油与天然气危机的最大赢家——并非美国战争策划者与为战争辩护的评论员原先预期的输家，即中国。
7.美国国内正当性危机
特朗普自身的政治联盟，正因战争倦怠与经济成本而进一步分裂。对军事过度扩张（以及军火耗尽）与外交惨败的批评，如今甚至在保守派与亲特朗普媒体及智库中也愈发明显。
这些声音正聚焦于一段向内重整的时期——削减对外援助、关闭海外基地，并重新界定总统的战争权力。而这种趋势，很可能延续至11月中期选举之后。美国仍将是一个强国，但它将不得不像一般大国那样行事——更具反应性，而非霸权性。
新世界秩序将会是什么模样？
通往新世界秩序的转型，不太可能和平或线性进行。它可能伴随代理人冲突、货币战争与制度衰败。然而，其核心方向十分明确：从以美国为中心的等级秩序与霸权体系，转向一种没有任何单一强权能够主导规则的、多极竞逐平衡。
虽然美国、中国与俄罗斯仍将是关键玩家，但更多积极进取的中等强国，也将寻求在这种多重结盟、交易导向的新秩序中扮演角色。现有与潜在的中等强国包括印度、巴西、印尼、土耳其、沙地阿拉伯、以色列、南非、加拿大、日本与韩国。中国在软实力与硬实力上的崛起，将确保其在未来任何版本的新世界秩序中，都处于领先地位。
那些较少受制于美国的国家，也可望借助金砖组织的经济与地缘政治影响力，建立一个较少暴力、更加稳定的多重结盟世界。目前，金砖组织仍是一股正在演化中的政治与经济力量；但随著其发展成熟，它有能力利用其庞大人口规模与日益增强的金融独立性，重塑全球治理，推动多极世界秩序。
这将直接挑战以西方、尤其美国主导的霸权体系，以及其虚伪与双重标准，而这些问题，最近已因西方对加沙地区种族灭绝政策的震耳欲聋沉默暴露无遗；在该事件中，以美国、英国与欧盟成员国为首的西方国家，向以色列提供了军事、政治与财政支持。
特朗普对伊朗的战争，虽不是这场地缘政治转变的根本原因，但却是让旧秩序再也无法维持下去的最后催化剂。
林德宜《特朗普如何塑造新世界秩序》原文：How Trump Is Helping Shape A New World Order
Whatever the terms of the agreement with Iran that President Donald Trump can wrangle and trumpet in a disastrous war he initiated and has now retreated from, it is clear that he personally and his administration's foreign policy are the biggest casualties in the geopolitical gyrations associated with his MAGA mission.
What is emerging now is a period of transition to a new world order that will contain the following key elements marking the end of American exceptionalism and hegemonic control of the global system.
1. A Multipolar Power Architecture
The United States (U.S.) will no longer be the sole or primary security guarantor in the Middle East and Asia Pacific, the two most contested regions of the world. China, Russia, and regional powers will fill vacuums through competing alliances, ad-hoc deals, and localized spheres of influence. The post-World War II "rules-based order" will give way to transactional, multi-aligned blocs.
2. De-Dollarization & Parallel Financial Systems
The joint U.S.and Israel conducted war - seen as illegal, dangerous and a breach of international law by most governments, including the U.S. strongest allies - is accelerating efforts by nations to settle trade in non-dollar currencies. The prospect of gold, digital yuan, or a new reserve basket emerging to fragment global finance is more likely now. While there has not been a collapse of the U.S. dollar's role as the primary global currency, the loss of its "exorbitant privilege" of low cost borrowing through printing and monopoly of the world's reserve currency is one of the most consequential war aftershocks. This will weigh heavily on American financial strength and bring the depreciation of U.S.financial assets.
3. Weakened Transatlantic & Asian Alliances
NATO and U.S. security allies in Asia (Japan,Taiwan, South Korea, Australia) are distancing themselves from an America First unpredictable Washington that launched a unilateral war in which they were not consulted. All are now suffering from the collateral impact of elevated oil and gas prices and supply line disruption. Some of the European powers are pursuing more independent defense and diplomatic tracks, while Asia Pacific nations are deepening economic ties with China to hedge against U.S. volatility.
4. Rise of Non-State & Regional Players
With great-power competition gridlocking the UN, regional organizations (African Union, ASEAN, Gulf Cooperation Council, Eurasian Economic Union) are working to gain authority and consensus on security, trade, and climate. Hybrid actors - private security firms, tech platforms, and cartels - are probing for quasi-diplomatic power.
5. Norm Shift on Sovereignty & Intervention
Trump's war has discredited the "preventive war" doctrine and unilateral intervention which has been a staple of post WWII Western foreign policy and geopolitics. An emerging norm is appearing to favor sovereignty, non-interference, and conditional neutrality - in effect weakening U.S.and Western style democracy and ‘freedom’ promotion. This will also imply rejecting deputy sheriffs’ roles to enhance American and Western dominance. International law is tilting toward non-punitive mediation to further the cause of peace and act to forestall or defuse ruinous wars such as in the case of Iran in which the war costs (human, economic, reputational) have outweighed any tactical gain.
6. Energy & Resource Realignment
A green wave tsunami is in the making. This is not only about climate change. The closure of the Strait of Hormuz effectively ended the era of "optional" energy security, turning the green transition into a survival imperative for global economies. Green transitions will accelerate as nations seek to reduce strategic vulnerability tied to fossil fuel chokepoints. The big winner of the oil and gas crunch - and not the loser as anticipated by American war planners and commentators looking to justify the war to local constituents - is China.
7. Domestic Legitimacy Crisis in the U.S.
Trump's own coalition is fracturing further over war fatigue and economic costs. Critics of military overstretch (and munition depletion) and the crushing diplomatic defeat are now prominent even in conservative and pro Trump media and think tanks. They are focusing on a period of inward restructuring - reducing foreign aid, closing bases, and rewriting executive war powers. This is likely to go well beyond the November midterm elections. The U.S. will remain powerful but will have to act more like a normal great power - reactive, and less hegemonic.
What Will The New World Order Look Like
The transition to a new world order is unlikely to be peaceful or linear. It could feature proxy conflicts, currency wars, and institutional decay. But the core movement and direction is clear: from the U.S.-centric hierarchy and hegemony to a contested, multipolar equilibrium where no single power dictates terms.
While the U.S., China and Russia will remain key players, assertive middle powers will be looking for a role in shaping this new order of multi-aligned transactionalism. Established and potential middle power candidates include India, Brazil, Indonesia,Turkey, Saudi Arabia, Israel, South Africa, Canada, Japan and South Korea. China’s rise in both soft and hard power will ensure that it will have a lead position in whatever variant of the new world order emerges.
Nations that are less hampered by apron strings to the U.S. can also be expected to leverage on the economic and geopolitical weight of BRICS+ to create a less violent and more stable world of multiple alignments. For now, BRICS+ is an evolving political and economic force. More developed, it should be able to leverage its combined demographics and growing financial independence to reshape global governance toward a multipolar world order.
This can directly challenge Western-centric, U.S.- led hegemony with its duplicity and double standards most recently exposed by its deafening silence on the Israeli policy of genocide in Gaza where Western nations, led by the U.S., UK, and EU members, have provided military, political, and financial support for the Israeli actions.
Trump's war with Iran, though not the cause of this geopolitical shift, is the final catalyst that has made the old order impossible to sustain.
