Suicide bombers don't do strategy. They are pure tactics.
Would you want your long term planning to be done by a guy killing himself tomorrow?
Not sure what you mean MH. Strategy is about deciding what tactics to use.
In the bombings in Sri Lanka that took planning which is strategy and then tactics which is the practical application of the strategy.
The two are inter-linked.
If you mean genuinely insane people who are spontaneous when they attack, then I think I might agree with you. However what we know is the vast majority of suicide attacks and bombings are pre-meditated.
In the Sri Lanka case the President appears to not have passed on intelligence warnings from the Indian intelligence service to his Prime Minister since the two don't speak and hate each other and so although Sri Lanka was warned of impending attacks they sat on the info and did nothing.
What this means is you will see the Sri Lankan military now rule the nation and once again terrorists undermine a democratic government.
From the sounds of it, Sri Lanka will have military rule and severe restrictions on freedom of speech and mobility now as a result of these attacks.
Once again a bunch of extremists in the name of Islam have engaged in terror.
This will ramp up tensions and distrust of all Muslims in Sri Lanka. This is a relatively recent phenomena because as everyone knows the North-South civil split between Senhalese (Bhuddist) and Tamil (Hindu) was never about religion In fact Christians, Hindus, Bhuddists in Sri Lanka as well as Muslims did not get into religious wars-it was over other things the North and South fought.
This kind of development has to add to tensions between India and Pakistan indirectly.
