President Donald Trump threatened to resume the war in Iran if he doesn't like the agreement with the country.
Speaking to press alongside Egyptian President Abdel-Fattah El-Sisi at the G7 conference in France, Trump said he will "go right back to dropping bombs" in such a scenario.
"I don't like it if they don't behave. We'll go right back to dropping bombs right smack in the middle of their head," Trump added.
He went on to note that the deal, which is set to be signed on Friday in Geneva, is "not final."
The agreement has been heavily scrutinized since its announcement. Even though the official content has not been released, different outlets reported on aspects of it, highlighting the financial relief Iran would get as a result.
Reuters noted that a $300 billion private fund to invest in Iran is included in the document, and more than half of that sum has already been committed. It detailed that the fund is a private investment vehicle, rather than a reconstruction or reparations program, and won't include government funding. Companies based in the U.S., the Gulf and elsewhere have already pledged financing.
Iran and Hezbollah have also said that Tehran's agreement with the U.S. requires Israel to withdraw from Lebanon, something the country has rejected doing.
Iranian Foreign Minister Abbas Araghchi said the presence of Israeli forces in the country would be a violation of the agreement.
"When we reached a ceasefire, we declared it across all fronts, with particular emphasis on Lebanon," Araghchi told press.
"An important point I want to emphasize is that, in our view, the two parties to this memorandum of understanding are the United States and Israel on one side, and Iran and Hezbollah on the other," he added.
Elsewhere, the country's deputy foreign minister, Majid Takht-Ravanchi, said the memorandum will include a mechanism that would be triggered should Israel "violate the agreement."
"If the Zionist regime violates the agreement, then — since the United States has committed on behalf of its partners in this understanding to ending the war on all fronts, including Lebanon — the mechanism set out in the memorandum will be activated," he said. It was not clear what the official was referring to.
Israel, however, has rejected such a possibility. The country's defense minister, Israel Katz, said the country won't withdraw from seized Lebanese territory despite the tentative agreement.
Speaking to press after the deal was announced, Katz also warned that if Iran attacks Israel in retaliation for strikes in Lebanon, it will respond "with full force" and won't relent on its goal "despite all the existing pressures and those that will still come."
