evidence: LONDON (AP) — Britain has reasserted its sovereignty over the Falkland Islands after Argentina pulled out of a cooperation agreement and demanded new talks over the South Atlantic territory that sparked a 1982 war between the two countries. [...] "The Falkland Islands are British," Cleverly tweeted late Friday. "Islanders have the right to decide their own future — they have chosen to remain a self-governing U.K. Overseas Territory.’’ Earlier, Cafiero said he told Cleverly that Argentina had decided to pull out of a 2016 agreement in which the the two countries pledged to work together on a variety of issues. While that agreement sought to improve cooperation in the South Atlantic, both sides continued to assert their claims to sovereignty over the Falkland Islands, known as Islas Malvinas in Argentina.
