Every Rohingya refugee I spoke to when I was in Cox's Bazar said the same thing: “We want to go back home.” When I went to Rakhine State and to Sittwe, I spoke to IDPs, internally displaced people, who've been kind of herded into what look like camps—these really horrific spaces—and all of them want to stay in Rakhine State, to go back to their farms.
To your question as to whether it's safe for them to do so, it won't be safe until and unless there's a mechanism to guarantee their safety, leveraged by the international community. Back to Sameer's question on what Canada can do, Canada has done quite well, but this needs a wider coalition of international actors, who can say to the Government of Burma—the Government of Myanmar—that this group has to be afforded their rights.
Is it safe to do so now? I don't think so.
