Tim Walz, the Democratic Vice Presidential Candidate, has criticized ex-President Donald Trump’s decision to withdraw from former President Barack Obama’s Iran nuclear deal, which he said paved the way for further Iranian nuclear development.

“Iran is closer to a nuclear weapon than they were before because of Donald Trump’s fickle leadership,” Walz said.

He argued that the United States needs “the steady leadership that Kamala Harris is providing” to navigate the Middle East conflict.

“A nearly 80-year-old Donald Trump talking about crowd sizes is not what we need in this moment,” Walz said.

Iran launched almost 200 retaliatory missiles on Israel earlier today, in an act that U.S. officials called “a significant escalation.”

The strikes were in response to the recent Israeli military campaign in Lebanon that killed more than 1,000 people, including Hezbollah leader Hasan Nasrallah. There were no fatalities in Israel from the attack, but one Palestinian civilian was killed in the West Bank.

Vance dodged questions on whether he believed Trump’s withdrawal from the Iran nuclear deal was a mistake.

Instead, Vance reiterated his claim that Trump delivered “stability” in the region through deterrence, saying that foreign agents “were afraid of stepping out of line.”
