Does not matter what Myanmar wants.
World can see that there is clearly a genocide going on in Myanmar.
No important country(US,EU, China and Russia) will sanction BD for attacking Myanmar,
as BD will have the moral high ground by saying it is obligated to stop an ongoing genocide.
Myanmar can only drop a few bombs here or there with their airforce(which is neither large or sophisticated enough to do any major damage to BD) but they will get defeated by BD in their own turf with the loss of northern Arakhan if not the whole of it. BD is a professional army while Myanmar is pretty much rag-tag - you can tell the difference by looking at the uniforms and equipment worn by the two armies.
