Guys, let us step back a little and think about it for a while.
Incidents like killing / bombing / mass destructions in India are considerably on a little less scale - compared to situation in Israel and Lebanon etc.,
It is this seeds of suspicion that the enemy is planting in our mind that we should worry about. Whether the recent 'suspected' terrorists arrested from Karnataka were successful or to what percentage, they would have been successful etc., one clear thing is emerging as a pattern:
"The enemy is getting away with planting the seeds of hatred amongst us and disrupting our socio-economic fabric. By making us constantly wonder if my neighbor is into some illegal activities if I don't see him for long (May be he works in night-shifts and sleeps during the day!). We should not fall prey to this. We must keep our heads high and live our lives peacefully"
