Why is Sigrid Kaag on the Board of Peace?

The Gaza Executive Board of the Board of Peace has three European members: Sigrid Kaag, Tony Blair and Nickolay Mladenov.

As a former diplomat (career at the United Nations) and politician (deputy prime minister of the Netherlands from 2022-2024 and leader of a centrist liberal party from 2020-2023), Sigrid Kaag's decision has de facto brought a semblance of respectability to this Board that makes it now easier for other European countries to join.

Am I the only one who is perplexed by this decision by Sigrid Kaag?
