Former U.S. Secretary of State John Kerry on Tuesday criticized President Donald Trump’s decision to pull out of the 2015 nuclear deal, warning the decision places Israel at risk.

"Today's announcement weakens our security, breaks America's word, isolates us from our European allies, puts Israel at greater risk, empowers Iran's hardliners, and reduces our global leverage to address Tehran's misbehavior, while damaging the ability of future administrations to make international agreements," Kerry said in a statement.

"No rhetoric is required. The facts speak for themselves. Instead of building on unprecedented nonproliferation verification measures, this decision risks throwing them away and dragging the world back to the brink we faced a few years ago," he added.

“The extent of the damage will depend on what Europe can do to hold the nuclear agreement together, and it will depend on Iran’s reaction. America should never have to outsource those stakes to any other country. This is not in America’s interests. We should all hope the world can preserve the nuclear agreement,” concluded Kerry.

Earlier this week, Trump blasted Kerry over reports that he had advised Iranian officials in an attempt to save the Iran nuclear deal.

"The United States does not need John Kerry’s possibly illegal Shadow Diplomacy on the very badly negotiated Iran Deal. He was the one that created this MESS in the first place!" tweeted Trump.

The President was responding to a report in the Boston Globe stating that Kerry met with Iranian Foreign Minister Mohammed Zarif two weeks ago in an attempt to save the Iran deal.

Responding to Trump, a spokesman for the former Secretary of State pushed back against his remarks.

"I think every American would want every voice possible urging Iran to remain in compliance with the nuclear agreement that prevented a war. Secretary Kerry stays in touch with his former counterparts around the world just like every previous Secretary of State," said the spokesman.

"Like America's closest allies, he believes it is important that the nuclear agreement, which took the world years to negotiate, remain effective as countries focus on stability in the region," added the statement.
