Isolated strikes against North Korea do not solve anything. North Korea is like a landmine on China's doorstep - we need to detonate it in a way that is as damaging to China as possible. Then we need to "strongly guide" South Korea to establish an individualistic, constitutionally Christian, anti-Confucian unified American client state, establishing a beachhead of liberty on China's doorstep. Recognize Taiwan the very next day and provide moral leadership for other free countries to do the same. Then get Japan to repeal the pacifist clauses of their constitution and encourage them to embrace their proud military heritage and greatly expand their offensive capabilities.
The dragon must be slain. Within 10 years, we will reach a point of no return where we will inevitably be resigned to Chinese global hegemony within the next 50 years.
China kneecapped itself with the 1 child policy. Theyll only ever be a regional hegemon, unless we accidentally nuke ourselves.
