If we follow your logic, that would be start of insanity. So according to your logic, when there is a robbery in a house, you want to blame the victim that it failed to defend against robbers and when a women is raped, won't you want to blame her for she failing to defend herself against rapist?
Wana see how it would look on India? All of Indian blame of cross-border infiltration and terrorism would be on India and even terrorist incident like Mumbai would be solely and entirely India's fault! You wana live with that?
It work both ways - when Pakistan is identifying RAW and asking India to refrain from interference, India must - or there will be repercussions and Pakistan too will utilize Indian fault lines to rip it - and for the second part, we are prepared to eliminate terrorist scums in Pakistan who become 'triggers' to propagate Indian terrorism designs. There is also a need to improve security apparatus - just like India identified its loop holes after Mumbai but that doesn't mean we stop holding Indian RAW responsible for their support of terrorism.
