Former President Jimmy Carter's state funeral this week is expected to draw a significant number of former presidents, potentially the largest gathering of the group since 2018. The event highlights the complex and sometimes surprising relationships that develop among former presidents, transcending partisan divides.

Carter's relationship with Gerald Ford, his presidential opponent, stands out. Their post-presidency friendship was characterized by close camaraderie, evident in frequent road trips and shared experiences. Contrastingly, Carter's relationships with other former presidents weren't always as amicable.

Despite his often-outsider status, Carter played a crucial role in mediating conflicts and promoting peacemaking. His influence extended across administrations, benefiting from a unique stature and close ties with international figures. His interventions averted potential conflicts and secured diplomatic breakthroughs, highlighting his substantial contributions.

Carter's approach, however, was not without its challenges. He was known for his strong opinions and independence, which sometimes clashed with those of other former presidents. Accounts from those close to Carter suggest he could be both invaluable and frustrating depending on the context. Former presidents often bonded over the idiosyncrasies and impact of Jimmy Carter.

Illustrative of Carter's interventions are instances such as preventing a U.S. invasion of Haiti, and brokering peace in Nicaragua. In these instances, Carter's efforts secured diplomatic solutions, preventing bloodshed and safeguarding numerous lives. He accomplished this, in part, through personal interactions with international leaders, often in informal and unusual settings.

For example, Carter's negotiation with a Nicaraguan leader took place in a backyard. His ability to engage directly with leaders across the political spectrum allowed him to achieve impactful results. Yet, he wasn't always favored by the sitting president. Carter's relationships with presidents like Reagan and Clinton were more complex and sometimes strained.

Despite the occasional friction, former presidents often recognized and appreciated Carter's contributions, even if they found him challenging. The interactions demonstrate the complexities of relationships that transcend political differences and acknowledge Carter's unique role.

Carter's relationships and legacy extend beyond his interactions with presidents, even to contemporary figures. Former President Donald Trump's reactions to Carter's centennial and death highlight both the enduring impact of Carter's political career and the diverse perspectives on his presidency.

Ultimately, Carter's legacy as a former president is marked by his unique contributions, complex relationships, and enduring impact on American diplomacy. His role in the post-presidency era, demonstrating that former rivals can find common ground—even as some may find him difficult to relate to.
