Notably more moderate than Administrator V'Las, Kuvak objected to V'Las' plans for an aerial bombardment of the T'Karath Sanctuary in order to eliminate the supposed threat of the Syrrannites, after they were wrongly accused of bombing the United Earth Embassy. (ENT: "Awakening")
Kuvak was further skeptical of evidence provided by V'Las that the Andorians had acquired Xindi technology and was understandably troubled when V'Las used this evidence as justification for launching a surprise invasion of Andoria. Even after it became clear that the Andorians were aware of the invasion, V'Las ignored Kuvak's urgings to recall their forces.
When Jonathan Archer and T'Pau presented the Kir'Shara to the High Command and accused V'Las of framing the Syrannites for the embassy bombing, Kuvak, who had barely been able to keep his emotions in check when he first saw the legendary artifact, physically incapacitated V'Las and ordered the invasion forces to withdraw.
Following the removal of V'Las from office and the dissolution of the High Command, Kuvak assumed a role in the new Vulcan government and promised a less supervisory role in relation to Earth. (ENT: "Kir'Shara")
