He also gave a sharp, yet unelaborated warning to Europe about another 60-day deadline Iran set Sunday.
"Within hours, the technical tasks will be done and enrichment above 3.67% will begin", Iran nuclear agency spokesman Behrouz Kamalvandi said.
Republican Senator, and key Trump ally, Lindsey Graham told CBS: "The most likely war would be between Israel and Iran if the Iranians started to reprocess and enrich in a manner that would accelerate their path to a bomb".
"But they know it's an upward trend", he said.
Iran is "doing a lot of bad things", Trump said but did not elaborate. However, it is far below the purity needed to make a nuclear weapon.
Tensions in the region have risen in recent weeks after oil tankers were attacked near the Strait of Hormuz and Iran downed an unmanned United States military surveillance drone.
The Joint Commission, chaired by the European Union's top diplomat Federica Mogherini, is made up of the remaining parties to the deal and was created to monitor implementation and address any issues.
Iran did leave some room for negotiations.
Shortly before Netanyahu posted his video, Iranian Foreign Minister Mohammad Javad Zarif accused "Bibi" of playing a part in scuppering both the 2015 deal and another agreement 10 years earlier, saying the Israeli PM "hasn't learned" from his past dealings with Iran.
But Kremlin spokesman Dmitry Peskov said it had warned that Trump's withdrawal from the pact would have negative consequences for global security. "I'm asking you, not to provoke but out of joint knowledge of history and what happens when aggressive totalitarian regimes can cross the threshold toward things that are very unsafe to us all".
But the European Union has no influence over the US financial sanctions that have proved so effective at deterring Iranian oil customers.
Speaking to the French Senate on July 9, Le Drian said that Iran's decision to surpass two accord thresholds - stockpiling weakly enriched uranium and enriching uranium beyond the 3.67 percent limit - amounts to "a bad reaction to a bad decision", a reference to the US withdrawal. France, Britain and Germany now must figure out how to respond.
The European parties to the deal along with the EU's diplomatic chief on Tuesday called on Tehran to reverse breaches of the agreement. "We wasted six years investing in our relationship with Europe", Majidi, a salesman in Tehran, told AFP, adding that the best option now is to pull out of the deal immediately. "We hope for the best, but the United States of America and our military are prepared to protect our interests and protect our personnel and our citizens in the region", he said.
In a news conference, senior Iranian officials said Tehran would keep reducing its commitments every 60 days unless signatories of the pact moved to protect it from U.S. sanctions, but they left the door open to diplomacy.
Germany says it is "extremely concerned" about Iran's announcement that it will break the limit on uranium enrichment set by the 2015 nuclear deal with world powers.
A senior official suggested Saturday that Iran would increase its enrichment rate to 5 percent, enough to produce fuel for its Bushehr nuclear reactor and other industries. He noted that the USA has not only unilaterally withdrawn from the agreement, but also through unilateral sanctions and "long arm jurisdiction", Washington is setting more bars for Iran and other sides to fulfill obligations under the deal.
