The Diplomat Season 4 ending breakdown: Grace commands attention at the G7 Summit as Kate makes a decisive move

The Diplomat Season 4 is streaming on Netflix. The latest season of the platform's political thriller series dealt with the fallout of a massive conspiracy involving President Grace Penn and Vice President Hal Wyler, who secretly orchestrated the theft of Russia's nuclear-powered weapon, the Poseidon, right under the UK's nose. Naturally, Kate Wyler was left to deal with the aftermath, which led to her game-changing decision in the finale.

According to The Cinemaholic, The Diplomat Season 4 featured a shocking moment when Grace was shot, allowing Hal to step into her position. While the President survived the attack, the incident led to her total transformation, resulting in erratic policies. After Grace's erratic actions led to Nicol Trowbridge's resignation, the new PM threatened to expose Grace and Hal's secret at the G7 Summit in Italy, which forced Grace to confess and manipulate the narrative in her favour.

Here is how Season 4 of The Diplomat ended.

The Diplomat Season 4 ending breakdown: Stuart's decision had major consequences

While Grace managed to survive the shooting in Windsor, she was not the same. Her husband, Todd, noticed she had become increasingly erratic in her decisions in The Diplomat Season 4. Things came to a head when Kate blackmailed Nicol Trowbridge, leading to his resignation, and Bethan Vaughn was appointed as the new PM. But the new PM posed a threat to Grace when the Russians asked to claim their dead and she agreed. Grace asked Kate to threaten the new PM into backing off her deal with the Russians, which made the whole situation messier.

Elsewhere, the Deputy Chief of Mission at the U.S. Embassy in London, Stuart Hayford, learned about Grace's blackmail and decided to share his reservations about her policies through the official diplomatic dissent channel, which would keep his identity anonymous. But after the Secretary of State, Miguel Ganon, unknowingly outed Stuart's identity in front of Grace, his position was compromised.

In The Diplomat Season 4, Grace ordered Stuart to be pulled back from London and brought to DC. The series' ending set up a dangerous future for him, one where he will be stuck in DC forever for daring to go against Grace's policies.

Grace's final move at the G7 Summit

Even after Vaughn was filled in on the whole Poseidon issue in The Diplomat Season 4, she did not back down from her deal with the Russians. On the other hand, Grace asked Kate to threaten the PM, warning that the US would send its warships if the UK did not back away from its deal with the Russians. While Kate tried to contain the situation, Grace's threats eventually reached Vaughn. Grace knew that America's threat to shoot at their own allies would not sit right with NATO and her country would likely be pushed out.

To steer the narrative in her direction in The Diplomat Season 4, Grace took the stage at the G7 Summit and confessed to taking Poseidon and suggesting sending warships to the UK coast.

This was a turning point in The Diplomat Season 4 as Grace smartly steered the narrative in her direction. She painted her actions of taking Poseidon as a bid to save British citizens and NATO’s territories. She turned Vaughn's threats on their head and painted her as a naive PM who allowed the Russians to enter her territory. Grace capped off her comments by indirectly threatening that the group requires America in order to sustain itself, making the country invincible.

The Diplomat Season 4 ended with Kate's resignation

In the final moments of The Diplomat Season 4, Kate resigned from her position as the US Ambassador to the UK at the Summit, with Hal, Billie and Ganon following suit. Grace's manipulation at the G7 Summit and her unjust actions to fire Stuart made Kate realize Grace's policies no longer aligned with her own and it was time to step back. While Kate's resignation might look like defeat, Grace's ambassador, the Secretary of State and the Chief of Staff all resigning together in front of the Summit was bad optics for the President of the United States.

Season 4 concluded with Kate and the group walking away after their resignation, ready to address the horde of reporters. While their conversation with the reporters was not revealed, their actions will have direct consequences for Grace's position and America's standing at the Summit.
