华盛顿讯——总统特朗普周四签署行政令，将安大略湖更名为“美利坚湖”，兑现了他本周早些时候在社交媒体上发出的威胁。
“我们将立即把安大略湖的名称改为美利坚湖，”总统在签署该命令前说道。
本周，特朗普在真相社交（Truth Social）上表示，美国正在“认真考虑”更改湖泊名称，并发布了一张划掉“安大略湖”字样的地图。他还称，美国不指望再“和安大略省做太多生意”。周四在椭圆形办公室宣布的这一举措，是特朗普在对加拿大发动贸易战期间的最新动作。
该命令要求内政部长道格·伯古姆更新地理名称信息系统（GNIS），以体现此次更名。地理名称信息系统与美国地名委员会合作，统一联邦使用的地理名称。总统无法强迫其他国家或国际机构使用“美利坚湖”这一名称，但可以要求联邦政府如此做。
有记者问及特朗普此次行政令向加拿大传递了何种信号。
“没有任何信号，”他说道，随后补充道，“如你所知，加拿大在贸易上占我们便宜已经很久了，非常非常可悲。甚至在军事方面也是如此。你知道，我们毫无代价地保卫加拿大。”
加拿大尚未对该行政令作出回应。
“安大略”一名源自原住民语言。据大湖文化知识中心介绍，该词来自易洛魁语“oniatarí:io”，意为“闪耀之湖”。

周六，针对葡萄酒和乳制品等部分加拿大进口商品的50%关税正式生效；周一，特朗普宣布将于明年1月起对所有加拿大钢铁和汽车进口商品加征50%关税。
作为回应，加拿大总理马克·卡尼宣布，从9月8日起，加拿大将对价值数十亿美元的美国商品开始征收最高达50%的对等关税。
特朗普还曾试图将北美最高峰——阿拉斯加的迪纳利峰——改回麦金利山。尽管联邦政府无法强迫其他国家或私营企业认可地理名称信息系统的更名结果，但当年特朗普试图将墨西哥湾更名为“美利坚湾”时，有一些私营实体采用了新名称。
尽管如此，在美联社拒绝使用“美利坚湾”这一名称后，白宫对其进行了惩罚，限制该社记者进入白宫和其他新闻机构均可进入的总统活动空间。
周四，特朗普还威胁要为一片大洋更名。
“现在我们只需要搞定一片大洋，”他说，“所以或许我们得把大西洋——或者——太平洋的名字改了。”
Trump signs executive order to rename Lake Ontario “Lake America”

Washington — President Trump on Thursday signed an executive order to rename Lake Ontario “Lake America,” making good on a threat he made on social media earlier this week.
“We’re going to be changing the name of Lake Ontario, effective immediately, to Lake America,” the president said before he signed the order.
On Truth Social, the president said this week that the U.S. was giving “serious consideration” to changing the name and posted a map that crossed out the label “Lake Ontario.” He also said the U.S. doesn’t expect to be “doing much business with Ontario any longer.” The announcement in the Oval Office Thursday is the president’s latest move amid his trade war with Canada.
The order directs Interior Secretary Doug Burgum to update the Geographic Names Information System to reflect the name change. The GNIS works with the U.S. Board on Geographic Names to standardize geographic names for federal use. The president can’t force other countries or international bodies to call it “Lake America,” but he can require the federal government to do so.
Mr. Trump was asked what message he’s sending to Canada with this executive order.
“No message,” he said, but added, “As you know, Canada has been ripping us off for a long time on trade, very, very sadly. Even the military. You know, we defend Canada for nothing.”
Canada has yet to respond to the executive order.
The name “Ontario” has Indigenous roots. The word comes from the Iroquoian word “oniatarí:io,” meaning “lake of shining waters,” according to the Center for Great Lakes Literacy.

On Saturday, 50% tariffs on some Canadian imports like wine and dairy kicked in, and on Monday, the president announced 50% tariffs on all Canadian steel and automotive imports starting in January.
In response, Canadian Prime Minister Mark Carney announcedthat starting Sept. 8, Canada will begin imposing matching tariffs of up to 50% on billions of dollars of U.S. goods.
Mr. Trump also sought to change North America’s highest mountain peak, Denali in Alaska, back to Mount McKinley. Although the federal government can’t force other countries or private businesses to recognize the GNIS, whenMr. Trump sought to change the Gulf of Mexicoto the “Gulf of America,” some private entities adopted the new name.
Still, the White House punished the Associated Press after it declined to use “Gulf of America,” restricting its reporters’ access to White House and presidential spaces available to other news outlets.
On Thursday, Mr. Trump threatened to rename an ocean, too.
“Now all we need is an ocean,” he said. “So maybe we’ll have to change the name of the Atlantic and—or— the Pacific.”
