加拿大遇上硬茬，撤回反关税广告无济于事，外媒：美国总统放狠话

Core Viewpoint - Canada, a close ally of the U.S., is facing significant economic challenges due to a trade war initiated by the U.S., particularly affecting Ontario, which plays a crucial role in Canada's economy [1][3]. Group 1: U.S.-Canada Trade Relations - Ontario has been severely impacted by the U.S. tariff war, prompting Canada to air an anti-tariff advertisement during a recent sports event, quoting former President Ronald Reagan on the negative effects of tariffs on the U.S. economy [1]. - Following the airing of the advertisement, the U.S. President expressed anger and threatened Canada, leading to Ontario's decision to withdraw the ad [1][3]. - The U.S. has imposed an additional 10% tariff on Canada, indicating a retaliatory stance and a desire for Canada to concede [3][5]. Group 2: U.S. Response and International Implications - The U.S. President's strong reaction to Canada's anti-tariff stance reflects a broader trend of the U.S. exerting pressure on its allies, including other Western nations, by imposing "reciprocal tariffs" [5]. - Canada's actions have not only angered the U.S. but have also raised concerns among other Western allies about the U.S.'s diminishing regard for its allies [5]. - The U.S. President's behavior suggests a tendency for retribution, reinforcing the notion that the U.S. maintains a dominant position in global affairs despite its rising national debt [9].
