Militants and government policy
The intention is reflected in the result. The barbaric bombings in Bangladesh are the result of long term patronisation of the terrorists. Now, everyone is surprised but one should know you reap as you sow. The direct government patronisation is reflected in their policy.
I wonder why people are surprised - they should not be as their elected government is the patron of the events. It is not rocket science to understand the cause and effects. People of Bangladesh blame US citizens for electing Bush for the second time, I guess it is time to face the mirror and see how ugly it looks there.
