Anti-Rohingya--certainly  NOT MUSLIM-- sentiment is very strong among the people in Burma. The army knows this all too well. If Aung San Suu Kyi were to make a statement that was not in accord with the people's sentiment, it would jeopardize her own standing with the people. The army would exploit this alienation, declare a NATIONAL EMERGENCY and seize power as the Constitution allows them to do. The people would support the army ON THIS.  Aung San Suu Kyi would be out of business. 
For the Burmese army world opinion was, is and will be entirely irrelevant. If bleeding hearts of the world were to respond with re-imposition of sanctions and  other punitive measures, the pro-Chinese faction in Burma's army would be much too pleased, for China would then be back in business. Like before, the army would run the show with support not only from China but also from neighboring Thailand, Singapore, and quite a few others.
