I think that's very true. I do imagine that governments, including the Canadian government, have on occasion found opportunities to raise their cases with Eritrean officials and that there are governments who have made it clear that they expect and want to see those prisoners released, but against a backdrop where we're not really seeing a wider significant, concerted global campaign of pressure on Eritrea with respect to these and other human rights concerns, it doesn't deliver positive results.
