Trump's speech was not the first time during the G7 that he has adopted a more critical tone toward Israeli Prime Minister Benjamin Netanyahu.
Netanyahu "has to be more responsible with respect to Lebanon", he said, adding that Israel's campaign against Hezbollah in the south had taken "too long".
He also reiterated that the Iran deal would "most likely" be signed Thursday or Friday and said a copy of the deal had been sent to Israel.
Trump has often been the centre of attention throughout his stay at the summit in the lakeside resort of Evian. In an unusual gesture, Macron invited Trump to dinner at the Palace of Versailles just outside Paris after the summit winds down on Wednesday afternoon.

Trump said he had accepted Macron's offer of dinner at Versailles, remarking that the former palace of France's "Sun King", Louis XIV, is adorned with "not gold leaf" but the "real deal".
Macron noted the evening at Versailles will not be a "gala" dinner.
AI on the agenda
The third and final day of the G7 summit focused on AI and social media, with CEOs from OpenAI, Anthropic and European rival Mistral meeting leaders for lunch earlier on Wednesday to discuss the security risks they pose, especially to youth.
The three-day summit of the leaders of Canada, France, Germany, Italy, Japan, the UK and the United States had focused intensely on Trump's deal to end the war with Iran and efforts to pressure Russia into brokering peace with Ukraine.
But on Wednesday the digital sphere took centre stage, with some European G7 members wanting more security in moves that have irked the United States.
OpenAI head Sam Altman, Anthropic chief Dario Amodei and their European rival Mistral AI's leader Arthur Mensch attended lunch with the leaders.
British Prime Minister Keir Starmer on Monday announced that children under 16 will be banned from using social media in the UK, with France also eyeing a similar ban. Australia put their own social media ban for under-16s into effect in December 2025.
The discussion at the G7 was focused on how to "improve cyber security and protect our children and our democracies", Macron had said in an Instagram video ahead of the summit.
Iran remains a key topic at the summit, with allies eager to question Trump over his deal with the Islamic Republic to end the Middle East war which is due to be signed in Switzerland on Friday.

Trump said the United States was under "no obligation" to invest in Iran after the deal, adding that its main focus was that Iran would not acquire a nuclear weapon and that "all hell" would "rain down" on the country if it did.
On Ukraine, Trump has moved to a more hostile stance against Moscow, saying Russia should "make a deal" and indicating Washington could re-impose waived sanctions.
