I would add some hypothetical scenarios.Just because current intrim leader is pro US don't mean it will stay that way. Unpopular government after revolution sometimes do get toppled again. Or sometimes it stays. There are too many factor at this point for me to predict the long term.
If we consider Dr. Yunus as total US puppet, he does not have the power to implement pro US policies.
First, he does not have a parliament. At interim government he will head, none of the other members are of his own choice.
Second, BNP is pro US. After winning election at 2002, they were in power for five years. Before that it was Awami league. At 2000-2001 sitting US president Clinton visited Bangladesh and asked for a base at Cox's bazaar which awami league denied. But they did not get it in BNP term either , because of strong anti US sentiment.
The man, Dr Yunus, can be an US puppet. But as head of government, he does not have legislative power to implement anything against public sentiment, which may lead to another violent uprising.
