Episode notes
Starlink Enabled The Drone Boat Revolution
- Starlink was the key enabler for Ukrainian drone boats, providing the range and control that previous radio systems couldn't.
- Ambrose recounts NATO exercises where GARC craft were trialled after Ukrainian innovations proved effective.
Full Spectrum Commodity Shock From The Gulf
- The Iran war is a full‑spectrum commodity crisis, not just an oil shock.
- Fertiliser, sulphur, helium and petrochemical feedstocks from the Gulf are disrupted, threatening planting seasons and chip production.
Nitrogen Fertiliser Supply Already Severely Disrupted
- Around 45% of the world's nitrogen fertiliser supply is currently disrupted because Gulf exports and Chinese/Russian curbs have tightened flows.
- Fertiliser is a just‑in‑time supply with no global stockpile, so missed spring planting will cut yields months later.
