in the commentaried of Srila Madhavacarya he has also made the same points, but added that Duryrodhana

is reminding Dhronacarya of his old rivalry with Drupas's son that is destined to kill him

Kesava Masmiri has added that Duryodhana is remining Dhronacarya that Dhrstadyumna is fighting against him though he learned military scince from him and should be shown no mercy
