A lip reader has decoded a heated exchange between President Donald Trump and French President Emmanuel Macron during a famously awkward handshake at the Gaza peace summit in Egypt. The handshake lasted about 26-30 seconds, with the two leaders gripping and tugging one another’s hands in a tense moment.

According to the lip reader, Trump questioned Macron’s sincerity, asking if he really agreed to the ceasefire plan. The conversation escalated with Trump accusing Macron of having “hurt” him, while Macron fired back with an “ominous warning” about what is to come.

Despite the fierce handshake, the summit marked a diplomatic milestone as a ceasefire ended years of deadly conflict, with the release of hostages and steps toward stability in Gaza. Trump touted the achievement as a ‘historic day’ and de-emphasized the idea of Palestinian statehood in favor of rebuilding Gaza.

The handshake rivalry between Trump and Macron is well-documented, with previous extended handshakes and embraces drawing global attention to their complicated relationship.
