:"If its a sensitivity about the military dicatorship in Argentina please say so", uh?? o_O 
 :The problem is that we have precisely zero sources to back the de facto timeline which was crafted entirely by a group of editors and their own analysis of sources. As you can see above with Kahastok's comment, we immediately run into problems when we try to decide what constitutes de facto control. So if you have sources (or a source) stating unequivocally the de facto control of the islands then please present it. 
 :What we can currently source is presence in the islands with no interpretation on our side required. Hence the proposed title Timeline of presence in the islands. Would you explain what makes no sense to you? Regards.
