On Tuesday, North Korea announced they have placed their artillery and rocket forces at the highest level combat posture. In other words, the North Korean military is on high alert.

North Korea released a statement to the Korean Central News Agency. The North Koreans said, "From this moment, the Supreme Command of the Korean People's Army will be putting in combat duty posture No. 1 all field artillery units including long-range artillery strategic rocket units that will target all enemy objects in U.S invasionary bases on its mainland, Hawaii and Guam."

The United States and South Korea have been engaging in joint military exercises in the Korean region. On Friday, the United States and South Korea signed a military pact that says the two nations will join up and respond to even the lowest provocation from the North. It is not clear if placing North Korea's military on high alert counts as provocation.

Hotair.com has an excerpt from the pact on their website. It reads, "Washington's mutual defense treaty with South Korea obligates the American military to fight to defend its ally if a war breaks out on the Korean Peninsula. The deal, signed Friday, defines what role the United States would play in dealing with what South Korean military officials called "local" provocations from the North, such as its shelling of a border island in 2010, which killed four South Koreans. The two allies said they had been working to improve their contingency plans ever since."

The office of the South Korean President Park Geun-hye responded to the statement made by the North Koreans. The South does not see North Korea's threat as credible.

"We have not detected any special movements in the North Korean military," South Korea said.

Right now it seems by placing their military on high alert North Korea is trying to scare the United States and South Korea with the harshest threats possible. North Korea placed its military on high alert in 1993, making the same threats, but did not follow up with any action.

Some are worried that North Korea will follow up on its threats this time, since they have been growing in frequency.

North Korea's anger comes from sanctions placed on the country by the United Nations. The UN reprimanded North Korea for testing nuclear weapons back in February.

The Dictatorship of North Korea's leader Kim Jong Un has yet to make any sort of significant military example of strength, other than the high alert threat.

Experts on North Korea believe he will feel compelled to do "something provocative" in order to prove the threats are not empty.
