The satellite launch facility at Tongchang-ri became dormant last August. Now satellite images show that rebuilding efforts began between 16 February and 2 March - either just before, during or immediately after Kim Jong-Un and Donald Trump abruptly ended their second summit on 28 February without signing a deal. Though the satellite images provide useful information, analysts and experts express caution against reading too much into them without sufficient intelligence to complement. Amid much media and ‘professional’ speculation, a senior research associate at the Centre for Nonproliferation Studies said, ‘It's possible that the activity at the facility is a chess move in North Korea's negotiating strategy to ratchet up pressure on Washington. The site, in the macro-sense, is very transparent and the North Koreans know we are always watching.’
