Update, 19 August: Per Yonhap:
South Korea suspended Wednesday the launch of its first space rocket with just under eight minutes remaining in the countdown due to a technical glitch.

Several factors – all driven by Pyongyang – are at work and have created an increasingly tense military situation on the peninsula. Additional long-range missile tests are expected, and naval clashes along the Northern Limit Line (NLL) are becoming more likely.

Some background: In January 2009, North Korea “voided” all political-military agreements with [...]

The importance of the three short-range missiles launched by North Korea on Monday and the two follow-on launches Tuesday is being overstated in the press and by some politicians; this week is not about short-range missiles but about an apparently functional nuclear device design.
North Korea generally conducts several short-range ground-to-ship or ship-to-ship missile flight [...]

North Korea launched a Taepo Dong 2 (TD-2) missile - probably a space launch vehicle (SLV) - on 05 April 2009. This was a launch of many firsts for Pyongyang, including releasing data about the launch beforehand and some actual video of the event afterwards:

In an attempt to quell speculation about a possible ICBM (a missile that typically delivers a nuclear warhead) test launch, North Korea recently signed related international treaties and announced it plans to launch a satellite in early April:
An international maritime agency official said Thursday that the [International Maritime Organization] has received a letter from [...]

The Taepo Dong 2 (TD-2) (대포동 2호) missile launch(es) North Korea likely is preparing for, and recent voiding of all political-military deals with South Korea, are part of Pyongyang’s long-term strategy of regime survival. While these actions also have less important near-terms goals – expressing displeasure with ROK President Lee Myung-bak’s relatively hard-line approach [...]

In 1999 the news on North Korea was both alarmist over North Korean antics and naively hopeful of peace suddenly breaking out. A decade later the news is still often alarmist - North Korea did test a nuclear device in 2006 after all - but less naive after decade of reneging on agreements and [...]

In March, North Korean missile tests were overreacted to. This week, officials in Seoul are calling similar tests, “routine.” My guess is Seoul is downplaying (or not over-hyping) the recent missile tests to avoid political complications in sending food aid soon.

North Korea fired three short range surface-to-surface missiles (SSM) from its West Coast this morning. Noting the expulsion of 11 South Korean officials from the Kaesong Industrial Complex yesterday, many pundits and the media were quick to declare the launches part as an orchestrated North Korean attempt to somehow influence South Korea and the [...]
