The US-Canada military alliance is facing a crisis due to President Trump’s tariffs on Canada and his threat to make it the 51st state. The move has caused goodwill between the two countries to evaporate, with security chiefs questioning whether their decades-old military cooperation will survive. As international competition heats up in the Arctic, where Russia is building bases and America eyes Greenland, analysts warn that US-Canada ties could worsen, potentially putting mutual defenses at risk from a Russian or Chinese nuclear attack.

California Governor Gavin Newsom has filed a lawsuit challenging President Donald Trump’s tariffs, marking the first time a state has sued over the levies. The suit argues that Trump's use of emergency powers to enact the tariffs exceeds his authority and cites previous Supreme Court rulings against Biden’s student debt forgiveness plan. California is home to a significant portion of US manufacturing and agricultural production, making it disproportionately affected by the tariffs.

Hong Kong has suspended its postal services to the United States amid the ongoing trade war with President Donald Trump. The Hongkong Post will no longer accept air mail packages bound for the US starting from April 27 and residents should expect to pay "exorbitant and unreasonable fees" if they still wish to deal with the US. An official government statement accused the US of being "unreasonable, bullying, and imposing tariffs abusively," stating that Hongkong Post will not collect any tariffs on behalf of the US.

The US is working hard to negotiate a "great" trade deal with the UK government led by Keir Starmer. According to JD Vance, Vice President Trump "really loves the United Kingdom" and has a cultural affinity with it. Trump imposed tariffs on imports earlier this month, and the UK government hopes to exempt itself from these tariffs. Vance expressed optimism that both sides can come to a mutually beneficial agreement, citing Trump's admiration for the Queen and King, as well as his business relationships in Britain.
