US Greenlights Ukraine's Long-Range Strikes, Sparking Tensions with Russia

President Biden has authorized Ukraine to use long-range U.S. missiles for strikes inside Russia, amid concerns of Russian escalation and the deployment of North Korean troops in Russia. Meanwhile, President-elect Trump opposes further U.S. military aid to Ukraine and plans to negotiate an end to the war. At the G20 summit in Brazil, Biden faces challenges as some of his endorsed measures lack support from the incoming Trump administration. Additionally, Trump's plan to combat fentanyl involves military action against Mexican drug cartels, raising concerns among experts about potential diplomatic fallout.
