I am afraid my friend that you are wrong. No security arrangement can not stop totally the fools who are ready to die while killing to citizens. India has reach experience to fight with these *** holes and that lesson we learnt very hard. RIP to dead.
Guys just look at the gem of the day here. This guy thinks that 'just' 90000 soldiers surrendered was less shamefull :rofl:
If that was surrender Pakistan is surrendering everyday. OBL raid for instance. (dont want to go off topic but just going by your defination.)
