Your BSF is coward because its troops are so apt to take innocent lives, but are shy of fighting our BGB. BGB never shoots at pleasure at any innocent crosser, but BSF always does. This makes the difference between the two nations. Coward people are fond pf torturing and killing innocents.
The only reason that Bangladesh doesn't retaliate to this killings is that your BGB is too inferior to face us. Yes , BGB doesn't shoot at anyone , only because no one is desperate enough to cross into your poor densely populated country. Maybe if Bangladesh is magically moved to some interior parts of Africa, then your BGB might get something to shoot at. But again , that might not happen , most probably , bangladeshis will start flooding Africa.
