President Donald Trump successfully facilitated a historic ceasefire between Israel and Iran on Monday. This development marked a significant pause in the intense military conflict between the two nations.
The ceasefire agreement, announced on Monday evening, officially commenced 12 hours later. This timeline allowed for final military preparations on both sides. However, the peace was immediately challenged by a series of missile attacks from Iran, leading to doubts among Israelis about the truce’s sustainability.
According to John Spencer, the executive director of the Urban Warfare Institute, delayed implementation of ceasefire agreements is not uncommon. Spencer explained in an interview with Fox News Digital that it is challenging to immediately halt ongoing military operations, such as aircraft in flight and troops in position.

Ending the Bosnian War, the U.S.-brokered Dayton Peace Accords established a phased timeline for troop withdrawals and political agreements. “That was a U.N., multiple countries signing into an agreement of what both sides would and wouldn’t do,” Spencer explained, contrasting it with the looser terms of the current Israel-Iran ceasefire.

Spencer also drew parallels to the 2014 war in Gaza. “Hamas would say, ‘Okay, we want a ceasefire… just until the next time they break the ceasefire,’” he said. Many of those agreements had 12- to 72-hour activation delays, similar to what is now seen with Iran.

Even more recently, during the ongoing Russia-Ukraine war, ceasefires were often brief and symbolic. “Putin said, ‘I want three days so I can do my parade,’” Spencer remarked, highlighting how temporary pauses can serve both strategic and political needs.
While past ceasefires were designed to slow escalation, Spencer sees this one as part of a broader strategic doctrine. “To help Israel in a way only United States could, that should be nonpartisan,” he said. “For the United States to do a very limited operation, without a single loss of American life… that’s unique.”

Spencer described the ceasefire as “an off-ramp” for both sides. “Ceasefire here means that both sides will stop shooting at each other. It doesn’t mean that Iran will stop chanting ‘Death to America and death to Israel,’” he said. “But the operations and hostilities have stopped.”
Despite the lack of formal terms or international enforcement, Spencer believes the agreement created a new precedent. “This established a new doctrine,” he said, citing Israel’s ability to dominate Iranian skies and the U.S. response to nuclear proliferation threats. “If Iran decides to rebuild some sites somewhere, the threats will be more present than ever.”
Spencer concluded, “It is a win. When red lines are really red lines, they are effective at deterrence.”
