华盛顿讯 参议院周三再次否决了一项旨在限制特朗普总统进一步对伊朗使用军事力量的战争权力决议，民主党人誓言将继续努力限制总统的权力。
一项将该议案从委员会提交全院表决的动议以47票对52票未获通过，共和党籍参议员、肯塔基州的兰德·保罗与民主党籍参议员、宾夕法尼亚州的约翰·费特曼打破了党派界限。
这是自2月28日战争爆发以来，参议院民主党人第四次就该议题推动投票。
这项由伊利诺伊州民主党参议员塔米·达克沃斯牵头提出的决议，原本要求特朗普总统“将美国武装部队从针对伊朗的敌对行动中撤出，除非获得战争宣言明确授权，或获得具体的军事使用授权”。
达克沃斯在周二的新闻发布会上表示，“我们不能任由这场混乱不受约束地发展下去”。
曾担任黑鹰直升机飞行员的达克沃斯说：“当我们的士兵继续为国家牺牲一切时，我们参议员需要尽到我们最基本的职责。”
这位伊利诺伊州民主党议员表示，参议院必须投票“结束特朗普发动的非法选择性战争”。

“我的共和党同僚们也面临选择，”达克沃斯说，“很简单：他们可以和我一起投票结束这场冲突，证明他们真的将美国放在首位，或者他们可以投票将特朗普的个人虚荣心放在首位。随着这场战争每天都变得越来越失控，很明显他们不能两者兼得。”
此次投票是参议院自总统在伊朗重新开放霍尔木兹海峡的最后期限前强化言论立场以来，首次就这场战争表态。特朗普此前还威胁称“整个文明都会消亡”。这一威胁遭到了民主党人和少数共和党人的广泛批评，例如阿拉斯加州参议员丽莎·穆尔科斯基就表示，这“不能被简单地当作是为了在与伊朗谈判中获取筹码而放出的狠话而被原谅”。几个小时后，总统宣布已与伊朗伊斯兰共和国达成为期两周的停火协议。
参议院少数党领袖查克·舒默在周三投票前敦促共和党人脱离本党立场，支持推进这项决议。
“共和党人已经三次否决这项决议了。但随着这场战争已经打了47天，看不到尽头，他们应该和我们一起支持这项决议，彻底结束这场战争，”舒默在参议院议场说道，“如果共和党人再次投反对票，我们将继续每周就这些决议发起投票，要么这场战争结束，要么共和党人拿出勇气对抗唐纳德·特朗普。”
共和党人将以60天期限为节点重新考虑支持态度
越来越多的共和党人暗示，如果战争在60天期限前仍未结束，他们可能会改变对这场战争的支持态度——根据1973年《战争权力决议》，未经国会授权的军事行动最长不得超过60天。
国会通过《战争权力决议》是为了应对越南战争，制衡总统未经立法机构同意就卷入武装冲突的权力。该决议要求总统在部署任何军事力量前“在一切可能的情况下”与国会磋商。
如果国会未批准战争宣言，总统必须在部署军队后48小时内向国会提交报告，并且将未经授权的军事行动时长限制在60天内。如果总统以书面形式向国会证明“出于美国武装部队安全相关的不可避免的军事必要性”，该期限可延长至90天。
犹他州共和党议员约翰·柯蒂斯本月早些时候在一篇专栏文章中写道，尽管他支持“总统为保护美国民众和利益所采取的行动”，但他不会支持“未经国会批准，将军事行动延长至60天以上”。
南达科他州共和党议员迈克·朗兹周二也提到了同样的时间线，他告诉记者：“我们预计政府将制定出7、8、9周后的行动计划。”
“我们必须了解下一步计划是什么，这是我们应尽的职责，”朗兹说。
当被问及在战争临近60天或90天期限时，国会是否应该授权这场战争时，参议院多数党领袖约翰·图恩表示，目前大多数共和党议员对美国在伊朗的行动成果“相当满意”。
“我认为政府有明确的目标和清晰的计划，如果他们能够贯彻执行，希望我们不必再回答这个问题，”他补充道。
Senate rejects 4th attempt to curb Trump’s war powers in Iran

Washington — The Senate on Wednesday defeated another war powers resolution aimed at curbing President Trump’s ability to use further military force against Iran, with Democrats vowing to keep trying to rein in the president.
A motion to discharge the measure from committee failed in a 47 to 52 vote, with Republican Sen. Rand Paul of Kentucky and Democratic Sen. John Fetterman of Pennsylvania crossing the aisle.
It was the fourth time Democrats in the Senate had forced a vote on the issue since the war began on Feb. 28.
The resolution, led by Democratic Sen. Tammy Duckworth of Illinois, would have directed President Trump “to remove the United States Armed Forces from hostilities within or against Iran, unless explicitly authorized by a declaration of war or a specific authorization for use of military force.”
Speaking at a news conference Tuesday, Duckworth said “we cannot let this chaos continue unchecked.”
“As our troops continue to sacrifice whatever is asked of them, we senators need to do the absolute minimum required of us,” Duckworth, a former Blackhawk helicopter pilot, said.
The Illinois Democrat said the Senate must vote to “end Trump’s illegal war of choice.”

“My Republican colleagues have a choice also,” Duckworth said. “It’s simple: they can vote with me to end this conflict and prove that they’re actually putting America first, or they can vote to put Trump’s ego first. With this war growing more and more out of control each day, it is clear that they cannot continue to do both.”
The vote marked the first time the Senate has weighed in on the war since the president ramped up his rhetoric ahead of a deadline for Iran to reopen the Strait of Hormuz, including with his threat last week that a “whole civilization will die.” The threat prompted widespread criticism from Democrats and a small number of Republicans, like Sen. Lisa Murkowski of Alaska, who said it “cannot be excused away as an attempt to gain leverage in negotiations with Iran.” Within hours, the president announced that a two-week ceasefire had been reached with the Islamic Republic.
Senate Minority Leader Chuck Schumer urged Republicans to break with their party and support advancing the resolution ahead of the vote on Wednesday.
“Republicans have voted against this resolution three times now. But as the war drags on for 47 days with no end in sight, they should join us on this resolution and end the war once and for all,” Schumer said on the Senate floor. “If the Republicans vote no again, we will continue to force votes on these resolutions every week until either this war ends or the Republicans get the courage to stand up to Donald Trump.”
Republicans eye 60-day mark to reconsider support
A growing number of Republicans have indicated that they could reverse their support for the war if it doesn’t end before the 60-day mark — the cap on any unauthorized engagements under the 1973 War Powers Resolution.
Congress passed the War Powers Resolution in response to the Vietnam War as a check on the president’s power to enter armed conflict without consent from the legislative branch. It requires the president to consult with Congress in “every possible instance” ahead of the introduction of any military forces.
The president must report to Congress within 48 hours of deploying forces if Congress hasn’t authorized a declaration of war, and it caps any unauthorized engagement at 60 days. That deadline can be extended to 90 days if the president certifies to Congress in writing that “unavoidable military necessity” related to the safety of U.S. armed forces requires it.
GOP Sen. John Curtis of Utah wrote in an op-ed earlier this month that while he supports “the president’s actions taken in defense of American lives and interests,” he would not support “ongoing military action beyond a 60-day window without congressional approval.”
Sen. Mike Rounds, a South Dakota Republican, pointed to the same timeline on Tuesday, telling reporters that “we do expect that the administration will be laying out their plan for after the end of seven, eight, nine weeks.”
“We have to know what the next steps are, and that’s a part of our due diligence,” Rounds said.
Asked about Congress authorizing the war as it approaches the 60- or 90-day mark, Senate Majority Leader John Thune said at this point, most of the GOP conference feels “pretty good” about what the U.S. has been able to achieve in Iran.
“I think the administration has a clear objective, a clear plan, and if they can execute on it, hopefully, that question won’t be a necessary one that we’ll have to answer,” he added.
