In the current refugee crisis context,not responding to burmese provocation was actually right decision.By creating military tension they wanted to burn the bridge with Bangladesh so that they can give excuse of bad relation with Bangladesh for not doing anything.burma is very much eager to paint the Rohingya refugee problem as bilateral one between burma and BD.By creating border incidence they wanted to blame BD for the current crisis and divert the attention of global community.But their plan failed.
But neglecting defence was our grave mistake.If our conventional military was powerful then these pesky burmese would have thought 10 times before doing anything like provocation.
