In 2002 you avenged by bringing whole of your army to our borders resulting in the death of hundreds of your soldiers. You avenged Pakistan by killing hundreds of your soldiers. Extremely pleasant but funny though.
As for 2008, I am yet to see you doing any surgical strike or cold strike after the attacks. Yeah if you avenged attacks using terrorists like TTP as they are your proxies than that was a very bad idea of avenging mumbai. Since with TTP getting whipped you might not have your proxies to fight for you and hence in future we don't have to worry about any such kind of "avenging" .
