The US has tested a missile defense system aimed at striking down intercontinental ballistic missiles, like the ones North Korea seeks to develop. The US army called the test result an "incredible accomplishment."

The Ground-based Midcourse Defense (GMD) interceptor was fired Tuesday from the Vandenberg Air Force Base in California. The US military announced that the test had been a success, with the interceptor striking a mock warhead over the Pacific Ocean.
Vice Admiral James Syring, director of the Pentagon's Missile Defense Agency, hailed the test as an "incredible success" and a crucial milestone in the US' missile defense program.
"This system is vitally important to the defense of our homeland, and this test demonstrates that we have a capable, credible deterrent against a very real threat," Syring added in a written statement.
Defending a North Korea attack
The interceptor, designed to intercept an intercontinental ballistic missile (ICBM), would be crucial in defending the US from a North Korean attack, should it come to that.
Riki Ellison, the founder of the Missile Defense Advocacy Alliance based near Washington which advocates for the development and deployment of missile defense systems to defend the United States, described the test as "vital."
"We are replicating our ability to defend the United States of America from North Korea, today," Ellison said.
The test came amid growing fears about North Korea's development of ICBMs capable of reaching the US. Pyongyang is also reported to be moving closer to being able to place a nuclear warhead on such a ballistic missile.
On Monday, the isolated communist country launched a ballistic missile that was believed to have traveled around 450 kilometers (280 miles) before falling into the Sea of Japan. The US Pacific Command said the short-range Scud-class ballistic missile was tracked for six minutes before it disappeared.
Syring admitted that, while Tuesday's test was a success, the Pentagon would continue to evaluate and improve on system performance based on data obtained during the test.
"We improve and learn from each test, regardless of the outcome. That's the reason we conduct them," said Pentagon spokesman Captain Jeff Davis.
"The system that we test today is a developmental system that's being flown for the first time and we look forward to understanding the results so we continue to mature the system and stay ahead of the threat," Davis added.
The US' missile defense program has been hampered by setbacks in recent years and come under steady criticism. While the US military GMD interceptors have been declared technically ready for combat since 2004, five out of nine tests since then have failed.

ICBM threat and North Korea's overall military strength
For years, the international community downplayed the threat of North Korea's military power. With the test launch of an intercontinental ballistic missile, it is clear that Pyongyang's military capabilities are growing.

Major achievement
In early June 2017, North Korea test-launched an intercontinental ballistic missile (ICBM) for the first time. Testing an ICBM marked a major military achievement for Pyongyang and a serious escalation of tensions with the United States and its allies in the region, particularly South Korea and Japan.

Trouble with warheads
At the time, defense experts said the ICBM could reach as far as the US states of Alaska and Hawaii. However, it was unclear if North Korea can field an ICBM capable of carrying a nuclear warhead on its cone that could survive reentry into the Earth's atmosphere. North Korean state media claimed the ICBM was capable of carrying a "large, heavy nuclear warhead" to any part of the United States.

Pyongyang's nuclear tests - six times and counting
The ICBM is believed to be a step forward in the North's nuclear program. Despite pressure from the international community, Pyongyang has made no secret of its nuclear ambitions. Alongside its ritual ballistic missile tests, North Korea has conducted nuclear tests on at least six occasions, including one in September 2017.

US running out of patience?
Responding to the first ICBM test with a show of force, the US and South Korean troops on conducted "deep strike" precision missile drills using Army Tactical Missile System (ATACMS) and the Republic of Korea's Hyunmoo Missile II. In April, the US sent its Carl Vinson aircraft carrier towards the Korean Peninsula, saying it was taking prudent measures against the North.

Testing the boundaries
Ignoring international condemnation, Pyongyang test-launched another rocket on July 28, 2017, just weeks after its first ICBM test. In both of the tests, North Korea used Hwasong-14 missile, but the second one reached a higher altitude and traveled a larger distance than the first one, according to the state media.

Whole of US within range?
Pyongyang conducted its third test November 29, using a newly developed Hwasong-15 missile. US, Japanese and South Korean officials said it rose to about 4,500 km (2,800 miles) and flew 960 kilometers (600 miles) over about 50 minutes before landing in Japan's exclusive economic zone off the country's coast.

One of the world's largest militaries
Apart from a developing missile and nuclear program, North Korea has a powerful army with 700,000 active troops and another 4.5 million in the reserves. It can call upon almost a quarter of its population to serve in the army at any given time. The North's bloated army is believed to outnumber its southern neighbor's by two-to-one.

Vast capabilities
According to the 2017 Global Firepower Index, the North has, as part of a far-reaching arsenal, 458 fighter aircraft, 5,025 combat tanks, 76 submarines, and 5,200,000 total military personnel. The picture above from 2013 shows leader Kim Jong Un ordering strategic rocket forces to be on standby to strike US and South Korean targets at any time.

Enemies all around
Alongside the United States, Pyongyang views its neighbors South Korea and Japan as its two other main enemies. North Korea has used US military exercises in the region as means of galvanizing its people, claiming that the exercises are dress rehearsals for an impending invasion.

Huge, colorful demonstrations of military might
Every year, hundreds of thousands of soldiers and citizens roll through the streets of the capital Pyongyang to take part in the North's military parades. Preparations for the rallies often begin months in advance, and the parades usually mark important anniversaries linked with the Communist Party or Kim Jong Un's family.
