Q: Washington (CNN) -- President Barack Obama used a Memorial Day ceremony to say it is time for America to properly welcome home Vietnam veterans and show them and their families the respect and gratitude they deserved but didn't receive decades ago. "You came home and sometimes were denigrated when you should have been celebrated," Obama said beneath a scorching sun at the Vietnam Veterans Memorial. "It was a national shame, a disgrace that should have never happened. That's why here today, we resolve that it will not happen again." The event, which launched a 13-year Vietnam War 50th anniversary commemoration, was the culmination of a day of somber events on the annual holiday honoring America's war dead.NEW: President Obama calls the denigration of Vietnam veterans a "national shame""America will be there for you," Obama tells veterans and their familiesMemorial Day launches a 13-year commemoration of the Vietnam War's 50th anniversaryObama lays a wreath to the fallen at Arlington National Cemetery

Q: (CNN) Somaliland President Ahmed Mohamed Silanyo recently claimed that more than one million citizens, out of the country's population of 3.4 million, had signed a petition calling for the international community to recognise Somaliland. Since 1991, and the collapse of the Siad Barre regime in Somalia, the region has declared itself independent. But should it? The examples of the secession of South Sudan and Eritrea raise serious questions and doubts about the outcomes of breakaway states. The general approach to calls for secession in Africa, as set out by the African Union (AU) and its predecessor the Organisation of African Unity, is that they should be opposed. The most frequently heard argument against secession is that granting the right to one country invites others to take the same step.Somaliland wants to be recognized as an independent countryCurrently 54 African countries are members of the UN
