Kim Jong-un likens Obama's remarks on North Korea to barking rabid dogs

North Korean leader Kim Jong-un thinks President Barack Obama's recent remarks on North Korea resembles the barking of rabid dogs.

In a veiled response to recent comments made by Obama suggesting Pyongyang regime is on its road to collapse, the belligerent leader warned his country is ready to confront "any war including a war by conventional armed forces and a nuclear war".

"We have no willingness to sit any longer with the rabid dogs openly barking that they will bring down by the method of bringing about 'changes' the socialist system, the cradle which our people consider dearer than their own lives," Kim said during a visit to a joint naval and air force simulated attack on US forces, according to the state-run Korean Central News Agency (KCNA).

The drill was specifically designed to practice a surprise attack on the "US imperialists' carrier" the news agency reported.

Tensions between Washington and Pyongyang have been rising in recent months, especially after the cyberattack on Sony Pictures, which the FBI says was carried out by North Korea.

Obama in a recent interview with YouTube, said: "We will keep on ratcheting the pressure, but part of what's happening is… the internet over time is going to be penetrating this country. Over time you will see a regime like this collapse."

This is not the first time North Korea has made bitter attacks on the US and its leaders. There have also been instances when Pyongyang's reports made racist remarks.
