Arming the Rohingya may not be a good solution, because there is only 800,000 left and that number may not be enough to support an insurgency. Also Islamic insurgency will raise the specter of "Islamic terror".
I recommend for Bangladesh to find ways to support the other insurgencies in Burma - Kachin, Shan, Mon and Karen. Thailand and USA may already be helping them, but everything has to be covert, with plausible deniability and absolutely no evidence of any connection to Bangladesh. Laos also has border, they might be helpful also, together with Vietnam, although I have no idea how they feel about Bamar's and if they may take the risk of getting involved. USA/West may help as many of these rebel groups are Christians and its a human rights issue.
Both China and India have adopted the vicious imperial Bamar Junta (Bamar's are 20-25 million) who have built up a big army with Chinese and Indian support in the last few decades. Their goal is to wipe out or assimilate all minorities. In case of Rohingya, the Bamar do not want to assimilate but purge all of them, using Buddhist Rakhines, who share their hatred of Rohingya's. Essentially they are our Asian version of Hitler and Nazi, right in our neighborhood. This shows the depravity of China and India, both countries have sold out these minorities who are fighting for their lives, for the sake of economic and strategic self interest. Only USA/West did not give in, because of Suu Kyi's instruction. But Suu Kyi herself is a Bamar and her political power is based on Bamar support, so her main concern is democracy of Bamar's. Bamar's I think more or less agree with Junta policy, because for them its an issue of ensuring Bamar domination. I don't think Suu Kyi matters that much in the big picture. It is the military junta, their Rakhine armed militia and the rebel insurgents that are the key players in this theater. The Junta is using Suu Kyi's "democratic" reputation and goodwill to open up the country for FDI. Note, Hitler was also elected as democratic leader.
In any case, we need better intelligence assets to get more real information from the fiield.
