China is not afraid but is exposing US double standards. If the US can share nuke tech with Australia then China can share nuke tech with Pakistan, Iran and North Korea.
Considering China already shares tech with those countries and even violate sanctions, not sure it matters much.
Conventional Missiles will not do the job. North Korea has nuke tipped missiles ready to pulverize South Korea and Japan. SK and Japan needs Nukes to defend. US needs to allow this.
Exactly, hence my question should Japan and South Korea be allowed such tech. They already have the ballistic missile tech but not nuclear. South Korea already has the ability to launch SLBMs from their recent submarine test.
