A much-hyped Iran peace deal looked set to be signed on Trump's birthday but is now stalling, which is bad for Trump's diplomacy and the Middle East.

• Trump said a peace deal with Iran would be signed Sunday, his 80th birthday, but Iran stayed cautious and the timing slipped.
• Israel struck a Hezbollah commander in Beirut in response to drone attacks, and Iran says this will not go unanswered.
• Negotiators accused Israel of sabotaging the deal, while the hardest part — Iran's nuclear program — was pushed to a later, tougher phase with 60 days of talks planned.
• The deal aims to fold Iran into the Abraham Accords, tying economies together to discourage future fighting, but trust in Iran's regime remains low.
• Trump also held a UFC cage fight on the White House lawn to mark his birthday, drawing a corruption lawsuit and thin crowds before he leaves for the G7.

Outlook: With fresh strikes and the nuclear issue unresolved, a signed deal this week looks unlikely and the back-and-forth attacks could continue.
