Shamsher Mobin Choudhury and Sabihuddin Ahmed as advisor are worthless and should be kicked out long ago. It is utter failure of BNP and even more unfortunate for general mass in Bangladesh that opposition party privately and publicly failed to deliver the message that when opposition and people in general are victim of regime brutality and killings, western stand for exerting pressure on opposition on shut down is not only far out of place but also strengthening hand of brutal and oppressive regime.
BUT it is also true US does not need BNP version of the information to understand autocratic and opressive situation, US has detail information about what Awami League atrocities and what it is doing to prevent caretaker govt. What I understood is US still conducting its policy doctrine on Bangladesh through Delhi. And we all aware active indian involvement in keeping Awami League subservient regime at any cost. US tone and noise about shutdown clearly directed to subdue already weaken opposition and oppressive Awami League regime is direct beneficiary of it. US is already pretending not seeing mass public anger against the Awami League regime. As such question is even if BNP communicated right message, would that be matter? Most likely not.
Fact is thus far BNP is wrongly advised that US and western countries will throw their weight behind caretaker govt demand for election but that is already proven to be dead WRONG; US or western govt would do no such thing while Awami League in power. In such situation BNP has to alter its strategy - not looking at US and west but go back to source of real power that is people. To the end US will side only with winning side, period.
