Last week, Israeli Prime Minister Benjamin Netanyahu addressed the US Congress, sending a clear message to Iran and its proxy forces Hezbollah and Hamas. While it wasn't a declaration of war, the absence of the word "ceasefire" from his vocabulary raised eyebrows. Since then, two key leaders of these groups have been killed, with Iran blaming Israel and vowing revenge. The United States, however, denies any knowledge or involvement in these events. How is this possible, and what does it mean for the already fragile peace in the Middle East?
