Why North Korea is testing missiles and Kim Jong Un is acting more aggressively

For the fourth time this year, North Korea is testing missiles on its west coast. Dictator Kim Jong Un is also arming himself rhetorically. Why? And what role does the old, new ally Russia play?

The Moscow-Pyongyang relationship appears to be developing splendidly. According to Western intelligence services, the Kremlin has released millions of dollars in frozen assets to support the isolated country’s increasingly assertive dictatorship, US media reports. The help is hardly a coincidence; in recent months, North Korea has delivered tons of ammunition and ballistic missiles to the Russian military for its war of aggression in Ukraine.
