In all honesty, most Americans don't even know what Bangladesh is. The name it self sounds so foreign, it has no "stan" at the end of it to make it sound like a country. To Americans it sounds like a fruit, some type of animal, or some dish or something.
India has growing economy, Bollywood, and Call centers to make it stand out to Americans. Pakistan well has terrorism, bombings, war in Afghanistan going for to make it stand out. Bangladesh is non-existant.
But I do admit, Bangladesh is strategically located. If Bangladesh plays its cards right, it can have India eating out of its hands and then America will take notice.
First thing Bangladesh can do is get the Chinese to open up a Naval Base in Bangladesh. The Indian reaction to that development will be priceless.
