唐纳德·特朗普周三晚间就伊朗问题发表全国讲话时，面临着极高的门槛。
根据最新民调，美国民众不仅对他的总统任期失去信心，而且对他发动的这场新战争感到反感，同时深切担忧战争对经济的影响。
中东和全球各地数百万人都想知道这场战争何时结束、将如何结束——甚至想知道他能否解决战争带来的混乱后果，其中包括伊朗封锁霍尔木兹海峡，这一行动有可能引发全球经济衰退。
在白宫十字大厅发表的20分钟讲话中，特朗普就发动战争的原因给出了他最连贯、最温和的解释，称在伊朗政权持续47年威胁美国之后，他不能允许这个“恐怖政权”拥有核武器。他解释了外交努力的失败，以及伊朗政权对本国人民的残酷镇压，借此发挥了他最核心的政治优势：展现强硬姿态。
这些说辞在一个多月前特朗普发动空袭时或许更具说服力。但此后数周，他反复无常、自相矛盾的战争目标言论，可能削弱了他此番更清晰阐述的战争正当性所带来的影响。
总统的部分说法与美国及西方情报评估结果相悖，例如他声称伊朗“距离拥有核武器仅一步之遥”，且可能很快就能拥有打击美国本土的导弹。他也未提供任何详实证据，让美国民众能够自行判断是非。
尽管如此，他还是给出了一个站得住脚的说法：经过美国和以色列声势浩大的空袭，伊朗的军事资产、在该地区制造混乱的能力，以及对美国及其盟友的威胁都已被摧毁。目前尚无外界能够知晓此次打击的规模，以及是否会引发政治裂痕，进而在未来削弱甚至推翻伊朗专制的革命政权。
但许多观察人士曾预期，总统会在此次讲话中明确提出战争的收尾方案。他不仅未能做到这一点，反而还暗示可能大幅升级军事行动。“接下来两到三周，我们将把他们打回他们该待的石器时代，”他说道。他还威胁称，如果德黑兰不接受他的和平协议要求，美国将袭击伊朗所有发电厂，并 targeting 其石油设施。
因此，很难断言这场讲话能安抚那些担忧战争走向的美国民众，或是缓解因战争引发能源危机而心神不宁的全球投资者。
总统自始至终都未阐明这场冲突的明确撤军战略——除非伊朗彻底投降这种可能性极低的情况出现。
为了淡化美国目前的参战投入，他辩称，迄今为止32天的战斗与美国在一战、二战、朝鲜战争、越南战争和伊拉克战争中投入的数年时间相比不值一提。但这种比较或许并未让民众安心，因为这暗示这场战争可能会比目前披露的时间更长。
他还警告称，是否维持石油供应将取决于美国的欧洲盟友——这些国家对波斯湾石油的依赖程度高于美国——这番言论势必引发恐慌，他坚称霍尔木兹海峡会“自然恢复畅通”，因为伊朗想要出售本国石油。总统声称外国国家可以轻松打破伊朗的有效封锁。但由于伊朗的导弹和无人机威胁，强大的美国海军尚未驶过这一关键的石油咽喉要道。
特朗普未能回答的关键问题
特朗普并未回答那些削弱其战争胜利说辞的最紧迫问题。
- 他声称，通过击毙包括阿亚图拉·阿里·哈梅内伊在内的伊朗高级领导人，他已经实现了政权更迭。但伊朗仍掌握在政权残余势力手中，这些势力可能比战前更加极端。
- 特朗普似乎暗示，他不会试图收缴可能让德黑兰重启核计划的高浓缩铀库存。他声称，美国的卫星监测将确保这些材料留在他去年轰炸过的伊朗核设施废墟中无人触碰。这将避免美军执行高风险任务。但这也让他“已终结核威胁”的承诺受到质疑。
- 他不愿开放霍尔木兹海峡，意味着全球经济仍可能受制于伊朗的要挟。这也意味着特朗普无法摆脱这场战争带来的后果。尽管美国拥有大量本土石油储备，但仍会受到全球能源市场波动的影响。美国人不会忘记，当前平均汽油价格已超过每加仑4美元。

特朗普的政治处境日益恶化
周三晚间，特朗普陷入了自己造成的政治和战略困境。
他杂乱无章的信息发布策略，以及通过社交媒体发布战争动态、发表反复无常且愤怒的言论的习惯，让他在两届任期内的总统任期支持率跌至历史低点。周三发表讲话前的一项新CNN/SSRS民调显示，他的支持率仅为35%。仅有34%的美国人认可他对伊朗采取军事行动的决定。约68%的人反对向伊朗派遣地面部队——这是特朗普迄今尚未采取的行动，但他周三并未排除这一选项。
这场战争还立即造成了痛苦的经济影响，公众信心暴跌便是明证。在此次民调中，特朗普在经济问题上的支持率仅为31%。约三分之二的美国人认为，他的政策加剧了经济状况恶化。
对于这位总统及其所在共和党来说，这些数据令人望而生畏——因为七个月后他们即将迎来一场艰难的中期选举。在任第二任期的总统中，若出现如此大幅的支持率和领导力信任度下滑，几乎鲜有能够挽回局面的。特朗普现在必须面对这样一种可能性：这场他几乎未曾解释清楚的战争，可能会毁掉他的总统任期，玷污他的政治遗产。
公众对特朗普经济政绩的怀疑也对他不利。甚至在战事爆发前，多数选民就已不买他“迎来新黄金时代”的吹捧，当时民众正面临高房价和高食品价格。
他周三晚间轻松地保证，汽油价格很快就会下跌，股市也会很快反弹回升，这听起来更像是一厢情愿，而非基于明确战争结束战略的表态。
很难断言这位总统清楚这场战争何时结束，或是战后世界将呈现何种面貌。因此，他或许几乎没有缓解全球对这场冲突的焦虑，也没能改善自身的政治困境。
Trump makes his best case for the war — but fails to ease worries about how it will end

Donald Trump faced a high bar Wednesday night in his national address on Iran.
He appeared before a country that has not only lost confidence in his presidency, according to the latest polls, but that has soured on his new war and is profoundly worried about its impact on the economy.
Millions of people in the Middle East and across the world want to know when the war will end and how — or even if — he’ll fix its tumultuous aftermath, including Iran’s closure of the Strait of Hormuz, which threatens a global recession.
In the 20-minute speech from the Cross Hall of the White House, Trump presented his most coherent and temperate explanation of why he went to war, arguing that he could not allow the “terrorists” in the Iranian regime to have a nuclear weapon after 47 years of threatening the United States. He explained the failure of diplomacy and the vicious crackdown by the regime against its own people, leaning into his best political asset: projecting strength.
Such arguments may have been more persuasive over a month ago, when Trump launched the onslaught. Weeks of subsequent whiplash filled by his contradictory and shifting war aims may blunt the impact of his more clearly articulated justifications for the war.
Some of the president’s claims — that Iran was “right at the doorstep” of a nuclear weapon and that it might soon have had a missile that could hit the US mainland — conflicted with US and Western intelligence assessments. And he did not offer any detailed evidence that might allow Americans to make up their own minds.
Still, he made a credible case that Iran’s military assets; its capacity to wreak havoc in the region; and its threat to the US and its allies had been devastated by a fearsome US and Israeli air campaign. No outsiders can yet know the scale of that damage and whether it will set off political cracks that could weaken or even topple the repressive Iranian revolutionary regime over time.
But many observers expected the president to use the address to point to a clear endgame for the war. Not only did he fail to do so, but he also raised the potential of a massive military escalation. “Over the next two to three weeks, we’re going to bring them back to the stone ages, where they belong,” he said. He also threatened to hit every Iranian electrical plant and to target its oil facilities if Tehran didn’t submit to his demands for a peace deal.
It’s therefore hard to conclude that his address will reassure Americans worried about where the war is going or global investors unsettled by the energy crisis the war has triggered.
At no point did the president lay out a clear exit strategy from the conflict — barring the unlikely prospect of complete Iranian capitulation.
In an attempt to downplay the current US commitment, he argued that the 32 days of combat so far paled in comparison with years invested by the United States in World War I, World War II, Korea, Vietnam and Iraq. But the comparisons may not have set minds at rest, since it implied this war may go on longer than has so far been acknowledged.
And his warning that it would be up to America’s European allies — who rely on oil from the Persian Gulf to a greater extent than the US — will cause alarm, as will his insistence that the strait will “open up naturally” because Iran will want to sell its oil. The president claimed it would be easy for foreign nations to dislodge Iran’s effective blockade. But the mighty US Navy is yet to sail through the critical oil choke point because of Iran’s missiles and drones.
The big questions Trump failed to answer
Trump did not answer the most pressing questions undermining his victory lap.
► He claimed he’d already effected regime change with the killing of top Iranian leaders, including Ayatollah Ali Khamenei. But Iran is still in the hands of regime remnants that may be even more radicalized than before the war.
► Trump seemed to imply that he would not seek to extract the stocks of highly enriched uranium that might allow Tehran to restart its nuclear program. He claimed that US satellite surveillance would mean this material would lie untouched in the wreckage of Iranian nuclear facilities that he bombed last year. This would obviate a high-risk mission for US troops. But it leaves his assurances that he ended the nuclear threat open to doubt.
► His reluctance to open the Strait of Hormuz means that the world economy could remain hostage to Iran’s leverage. And it will mean Trump can’t outrun the consequences of his war. While the US has its own vast oil reserves, it’s still subject to fluctuations in global energy markets. Americans don’t need reminding that average gasoline prices top $4 a gallon.

Trump’s political plight is worsening
The president went into Wednesday evening in a political and strategic corner of his own making.
His haphazard messaging and habit of providing war updates via social media and erratic, angry rhetoric have helped drive public confidence in his presidency near historic lows over his two terms. A new CNN/SSRS poll on Wednesday before the address showed his approval rating at 35%. Just 34% of Americans approve of the decision to take military action in Iran. Some 68% oppose sending ground troops into Iran — a step Trump is yet to take but did not rule out on Wednesday.
The war has also caused an immediate and painful economic impact that is reflected in plummeting public confidence. Trump’s approval rating on the economy in the new poll is just 31%. And roughly two-thirds of Americans say his policies are contributing to worsening conditions.
These are daunting numbers for a president and a Republican Party already facing a tough midterm election in just seven months. Second-term presidents who see such slumps in their popularity and confidence in their leadership rarely recover. Trump must now contemplate the possibility that a war he did little to explain could consume his presidency and stain his legacy.
The public’s skepticism of Trump’s economic record is also a liability for the president. Even before the fighting started, a majority of voters had rejected his lauding of a new golden age as they battled high housing and food prices.
His blithe assurances Wednesday night that gasoline prices would soon fall and that stocks would soon spike back up seemed more like wishful thinking than the product of a clear strategy to end the war.
It was hard to conclude that the president knows when the war will end or what the world will look like when it does. He may therefore have done little to ease global anxiety over the conflict or his own political plight.
