Iran live updates: Trump says 'no more Mr. Nice Guy' if Iran refuses nuclear deal

President Donald Trump on Tuesday issued an apparent rebuke of German Chancellor Friedrich Merz's criticism of American strategy in Iran, saying that the German leader doesn't "know what he's talking about."

Merz, Trump claimed, "thinks it's OK for Iran to have a Nuclear Weapon" -- something Merz did not say in his Monday criticism of the U.S.-Israel campaign.

"If Iran had a Nuclear Weapon, the whole World would be held hostage. I am doing something with Iran, right now, that other Nations, or Presidents, should have done long ago," Trump said.

"No wonder Germany is doing so poorly, both Economically, and otherwise," Trump added in the post.

Merz said at an event on Monday that the U.S. had "no strategy" in Iran and was "being humiliated by the Iranian state leadership."

The Trump administration is taking additional action against nearly three dozen entities and individuals accused of operating Iran's shadow banking networks.

The administration says these entities and individuals allow the Iranian regime to evade sanctions and pocket "tens of billions of dollars."

"By dismantling these financial channels, we advance the Administration's policy in the conflict with Iran and underscore our commitment to imposing maximum pressure on Iran," State Department spokesperson Tommy Pigott said in a statement.

Israel will continue to destroy terrorist infrastructure in southern Lebanon "just like in Gaza," Israeli Defense Minister Israel Katz said on Tuesday.

"Prime Minister Benjamin Netanyahu and I have instructed the IDF to destroy every terror infrastructure in the security zone up to the yellow line, below and above ground, just like in Gaza," Katz said.

"The IDF has now destroyed an underground terror infrastructure in Qantara, Lebanon, in a huge explosion, inside the new security zone," Katz said.

A ceasefire has in place since April 16 but strikes against Hezbollah in Lebanon have continued. Hezbollah has also continued to target Israeli troop positions in southern Lebanon.

Iran signaled Tuesday that it is not standing down in its dealings with the United States amid the war.

Iran said it does not consider the war over. Despite the ceasefire, Iran said it is actively updating targets, continuing training, and producing and upgrading weapons. "Conditions remain those of wartime," Mohammad Akraminia, Iranian Army spokesman, said on Tuesday.

Akraminia said Iran's response to future attacks from the U.S. would be severe.

"We have many cards we have not yet played. We possess new arenas of war, new tools, and new methods of fighting based on the experiences of the two previous wars. We have many cards we have not yet played. We possess new arenas of war, new tools, and new methods of fighting based on the experiences of the two previous wars. We can certainly respond to the enemy more decisively and more crushingly," he said. "We can certainly respond to the enemy more decisively and more crushingly."
