Here is the latest edition of “Five Things We Learned This Week” for May 17–23, 2025, highlighting significant global developments across various sectors.

🛑 1. UN Warns of Escalating Humanitarian Crisis in Gaza

UN Secretary-General António Guterres described the current stage of the Gaza conflict as possibly its “cruellest phase,” with Palestinians facing immense suffering amid escalating Israeli military operations. He warned that the entire population is at risk of famine and criticized the limited humanitarian aid reaching Gaza, citing that only a fraction of permitted aid trucks have reached those in need due to insecurity. In the past 24 hours, at least 60 people were killed, including strikes on Khan Younis, Deir al-Balah, and Jabaliya, with over 50 people still buried under rubble. UN agencies and aid groups have raised alarms about inadequate food and medical supplies, with over 9,000 children treated for malnutrition and the healthcare system near collapse—94% of hospitals are damaged or destroyed. Israeli airstrikes have also targeted hospitals, further straining emergency services. Despite easing an 11-week blockade, aid remains minimal, far below pre-war levels. International criticism of Israel’s military actions continues, with leaders calling for a ceasefire and increased humanitarian access. Meanwhile, discussions are underway among Western nations about formally recognizing the state of Palestine, adding a new diplomatic dimension to the ongoing crisis. 

💉 2. NHS England Launches World’s First Gonorrhoea Vaccine

On May 21, NHS England introduced the world’s first gonorrhoea vaccine, demonstrating an efficacy of 30–40%. This development aims to combat the rising rates of gonorrhoea infections and represents a significant advancement in public health efforts to control sexually transmitted infections. 

📉 3. Trump’s New Tariff Threats Shake Global Markets

President Donald Trump’s evolving trade policies continue to send shockwaves through global markets. After a brief period of de-escalation in the U.S.-China trade war, markets were rattled on May 23, 2025, when Trump threatened to impose a 25% tariff on Apple iPhones not manufactured in the U.S. and a 50% tariff on EU goods starting June 1. These moves undermined recent optimism following tariff reductions between the U.S. and China, which had reignited S&P 500 gains and stabilized investor sentiment. However, concerns about tariffs resurfaced alongside rising inflation, tepid economic growth, and persistent federal debt nearing 100% of GDP. Despite some temporary relief—such as tariff pauses and incentives for auto and tech firms—Trump’s unpredictable trade tactics, especially his criticism of Apple’s offshore manufacturing and pressure on trading partners like the UK and India, have reintroduced uncertainty. Furthermore, even with promising AI infrastructure investments from the Middle East, the U.S.-China relationship is strained by export restrictions and sanctions tied to Huawei’s semiconductor use. Economists warn these erratic policies could spur stagflation and erode S&P 500 earnings growth, highlighting the risks of Trump’s tariff-heavy strategy amid widening fiscal deficits and global trade tensions.
