Trump reopens GERD mediation; Sisi calls the Nile a red line
At the G7 Trump says the dam is causing Egypt 'tremendous problems' and offers to restart US Nile mediation, six months after Ethiopia inaugurated Africa's largest hydro project
Summary
At the G7 on 17 June, Donald Trump told El-Sisi the Grand Ethiopian Renaissance Dam is "causing tremendous problems for Egypt" and that "the Nile is getting a little emptier than it should be," offering to restart US-led mediation — a follow to his January letter to Sisi. This is the post-inauguration phase: Ethiopia inaugurated the GERD on 9 September 2025, now Africa's largest hydro project at over 5,000 MW with a reservoir up to 74 bcm. Egypt's position is unchanged — the Nile supplies 98% of its renewable water, "not a single drop" is negotiable, and it demands a legally binding filling and operation agreement that Ethiopia rejects as an infringement on its sovereignty. Addis Ababa (Abiy Ahmed) says operations follow seasonal hydrology and cause no downstream harm. The water file is the existential edge beneath Sisi's regional diplomacy.
By the numbers
- 17 June 2026 — Trump's GERD mediation offer at the G7 bilateral with Sisi.
- 9 Sep 2025 — GERD inauguration; >5,000 MW, reservoir up to 74 bcm.
- 98% — share of Egypt's renewable water from the Nile.
- 0 — "not a single drop" Egypt says it will concede.
Why it matters
US mediation has failed before, and analysts warn re-engagement could harden positions more than resolve them. But it hands Sisi a great-power ally on his most existential issue at the moment Egypt's economy is most fragile — leverage he can use even if a binding deal stays out of reach against Ethiopian resistance.
What to watch
- Whether Ethiopia agrees to any US-brokered process or rejects it outright.
- Reservoir operation through the flood season and any downstream impact.
- How Sisi uses the mediation offer domestically and with Gulf backers.
