Tillerson on north korea policy of strategic patience has ended

You're referring to the shift in the United States' policy towards North Korea.

In April 2017, then-Secretary of State Rex Tillerson announced that the US was ending its policy of "strategic patience" towards North Korea. This policy, which was initiated during the Obama administration, had been characterized by a lack of direct engagement with North Korea and a focus on increasing economic pressure through sanctions.

Tillerson's announcement marked a significant shift in the US approach, as the Trump administration sought to take a more confrontational stance towards North Korea's nuclear program. The new policy aimed to pressure North Korea to abandon its nuclear weapons and ballistic missile programs through a combination of diplomatic efforts, economic sanctions, and military deterrence.

The decision to end "strategic patience" was driven by North Korea's rapid progress in developing its nuclear and ballistic missile capabilities, as well as concerns about the potential threat these capabilities posed to the US and its allies. The Trump administration believed that a more assertive approach was necessary to prevent North Korea from becoming a nuclear-armed state.

Under the new policy, the US increased its military presence in the region, conducted joint military exercises with South Korea and Japan, and imposed additional sanctions on North Korea. The administration also engaged in diplomatic efforts, including talks with China and other regional powers, to pressure North Korea to change its behavior.

However, the policy shift did not lead to a significant change in North Korea's behavior, and the country continued to develop its nuclear and ballistic missile capabilities. The situation remains tense, with the US and North Korea engaged in a cycle of threats and counter-threats.

It's worth noting that Tillerson's announcement was made just before he was fired by President Trump in March 2018. Since then, the US has continued to pursue a policy of "maximum pressure" towards North Korea, which has included increased sanctions and diplomatic efforts to isolate the country.
