made. Satellite imagery of Sohae Launching Station Days after the summit ended, commercial satellite imagery indicated that reconstruction of the Sohae Satellite Launching Station, which previously appeared to be in the middle of dismantling by North Korea, may have been performed during the summit, and that the site could be operational. A senior U.S. State Department official acknowledged "some level of reassembly" but stopped short of concluding the site was operational. Town remarked: "Given how much has been done at this site, it looks like more than a couple days' worth of activity ... It's hard to say if it happened immediately after the summit and they just rushed everything — I guess it's possible — but it's more likely that it started just before." South Korean National Intelligence Service chief Suh Hoon said there was recent transport vehicle activity at the Sanumdong ICBM factory. Some analysts believed that the renewed activity at Sohae and Sanumdong was designed to pressure Washington back to the negotiating table, rather than to actually restart the nuclear testing program.
