What is North Korea Getting In Exchange For Helping Russia In Ukraine War?

North Korea and Russia recently entered a partnership agreement that includes amongst other things, defense cooperation in the event of an attack. North Korea has already been sending military support to Russia, to aid it in its ongoing war in Ukraine. But is Kim Jong Un of North Korea doing this out of the goodness of his heart? In exchange for giving military support to Russia, Kim could request from Russia, technologies for nuclear-powered submarines, technologies for nuclear weapons and intercontinental ballistic missile developments, satellite technologies, fighter jets and capabilities for other military equipment manufacturing. It remains to be seen the full extent of their cooperation.
