A nuclear deal with Iran is being signed this week, but the real fight is over a $300 billion reconstruction fund — bad news for taxpayers and Israel, good for Trump-linked dealmakers.

• The Trump administration may set up a $300 billion fund to rebuild Iran if it ends its nuclear program.
• It's unclear where the money comes from — Gulf states, unfrozen Iranian assets, or US taxpayers.
• What's signed is only a 60-day framework, not a final deal, and the hardest issues are unresolved.
• Israel and Netanyahu are alarmed, haven't seen the terms, and are scrambling to reach Trump.
• The likely prize is reconstruction contracts and control of Iran's oil, which is where critics say the deal really points.

Outlook: Expect 60 days of fighting over the money and the details, with Israel pushing to blow up the deal if the terms favor Iran.
