North Korea has called South Korea a 'fascistic dictatorship' after its short-lived martial law.
South Korea has democratic elections, while Kim Jong Un exerts near-total control over North Korea.
An article in North Korean state media also referred to South Korea's president as a "puppet."

North Korea has called South Korea a dictatorship after the latter's short-lived attempt at martial law.
Last week, South Korea's president, Yoon Suk-yeol, declared martial law in the country in a surprise announcement, citing the need to eliminate "anti-state" forces.
The unexpected decision was met with widespread protests, and hours later South Korea's parliament voted down the measure. Yoon's government quickly rescinded it.
In reality, North Korea is widely regarded as a global pariah due to Kim's authoritarian governance, whereas South Korea is recognized as a democratic nation.
