A US-Iran peace deal is falling apart as Israel pushes deeper into Lebanon, which is bad news for anyone hoping the Middle East wars wind down.

• Israel bombed dozens of sites in Lebanon and moved tanks and troops further in, even after agreeing to a ceasefire with Hezbollah.
• In response, Iran pulled its negotiators from Switzerland and JD Vance canceled the trip, stalling the talks.
• Iran then closed the Strait of Hormuz again, saying the deal was supposed to stop Israel's attacks on Lebanon.
• Much of US media and Congress are cheering the collapse, calling the deal a humiliation and pushing for war instead of peace.

Outlook: Peace depends on Trump and Vance pulling the US back from the fighting; if Israel keeps striking, the deal likely dies and the Hormuz shutdown squeezes oil.
