Why isn' more of the world being tough on Myanmar when they pull shit like this? That is my main question.
There are not many ways to be tough on Myanmar without causing a war which may be lost, and has a high probability of making everything worse. The situation in Burma is delicate. The authoritarian regime is strong but unstable and politically repressive, there are ongoing terrorist attacks in most states, with ongoing conflict in Kachin, Shan and Rakhine, in three individual separatist-state wars. This does not include all the lower scale conflicts on the borders of Burma and its neighbours in Bangladesh, Laos and China. The situation with other ethnic states remains volatile. The ability for foreign agents and journalists to act in Burma is severely curtailed. The Burmese mountains, forests and monsoon seasons are also some of the most formidable in the world, which means that even if the Chinese were not ambivalently keeping their eye on Burma, nations with great expeditionary capability like the USA might think twice about embarking upon an invasion which would make Vietnam seem pleasant by comparison. The international community's main hope came in the form of Aung San Syuu Kyi, who went from being a political prisoner to a great liberal proponent in an otherwise tightly controlled authoritarian regime. These hopes did not translate into any useful movement in Burma, as Aung San Syuu Kyi was elusive on the topic of the Rakhine cleansing.
The end result is inaction, because those that are not indifferent, do not capable options available. It is notable that even for all those who are knowledgeable of the Rakhine situation, they are not of the ethnic conflicts, terrorism, child soldiery that have pervaded this region since WWII and the partition of the Raj. Thus there is an element of Western media only selectively reporting when abuses align with its agenda, such as when Middle Eastern regimes transform from forces of stability into evil rogue states. In cynical terms,
the West only cared when Burma started pumping oil to China, bypassing US control of the straits of Malacca
