On 29 August North Korea launched a missile over Japan, saying that it was ‘the first step’ of military operations in the Pacific. State media also repeated threats to the US Pacific island of Guam, which it called ‘an advanced base of invasion’. Russia and China said that US military activity in the region was partly to blame for the increase in tensions. BBC correspondent Jonathan Marcus reported, ‘Launching a rocket over Japanese territory, with the possibility that it could deposit debris on Japanese soil, shows that Pyongyang is intent on maintaining its brinkmanship. However, it is noteworthy that North Korea did not make good on its threat to direct a missile towards the US Pacific territory of Guam - something that might well have precipitated a US military response.’ See also British Isles article 4, ‘Theresa May on North Korea’.
