After the execution of Jang Song Thaek, North Korea's number 2 guy, and uncle of Kim Jong Un, the Hermit Kingdom's leader, North Korea experts believe that the world is just seeing the beginning of more political executions in the future, according to a report by MSN News.

The popular Jang who served as mentor and father figure to North Korea's leader was executed after being accused of treason. According to North Korea's state-run media, Jang was a morally corrupt traitor who saw the death of Kim Jong Il, father of the current leader, as an opportunity to seize power.

"He dared not raise his head when Kim Il Sung and Kim Jong Il were alive," a news report aired in Seoul, South Korea said, while referring to Kim and his late father. The TV news report also claimed that Jang realized his "long-cherished goal, greed for power" when the older Kim died.

"If he has to go as high as purging and then executing Jang, it tells you that everything's not normal," Victor Cha, a former senior White House adviser on Asia, referring to the younger Kim, told MSN News.

Experts who are following developments in the authoritarian country for years were divided as regards events that took place. Some argue that the latest event involving Jang's execution is Kim's attempt to consolidate his power and a decisive show of strength. However, what has more weight and alarming is that the execution only shows how unpredictable Kim is as a leader.

"When you take out Jang, you're not taking out just one person - you're taking out scores if not hundreds of other people in the system," Cha said, believing also that the purge could spread and lead to more executions. "It's got to have some ripple effect."

According to South Korean intelligence officials, two of Jang's closest aides have already been executed last November.

"The removal of Jang from the seat of power shows that Kim Jong Un has the guts to hold onto power, and this might have shown his will to power, his willingness to get rid of anything that stands in his way," Narushige Michishita, a security expert at the National Graduate Institute for Policy Studies in Tokyo, told MSN News.
