North Korea's latest rocket has a striking resemblance to an advanced Russian design, according to experts who analyzed images of a gun test on Saturday morning .
The missile, called North Korea's "tactically routed weapon", seems superficially almost identical to the Russian Iskander rocket – a high-precision short-range weapon capable of hitting targets from over 150 miles away.
] Such a system has the potential to attack missile defense in South Korea and further escalate tensions in the region, as well as showing that North Korea is developing new weapon systems, even though President Trump is optimistic with North Korean leader Kim Jong Un.  "This Iskander-style rocket is one thing we need to worry about," says Melissa Hanham, a weapons expert at One Earth Future.
North Korea tested the weapon on May 4 as part of a "strike exercise" that includes the use of other weapons such as rocket artillery.It was the first published test of a rocket, be In April 2018, North Korea declared a voluntary moratorium on intercontinental long-range missile testing. The new rocket seems to be short range, which means it will not violate the moratorium.
Anything In this very interesting world, it is possible, but I believe that Kim Jong Un fully recognizes North Korea's great economic potential and does nothing to disturb or end it. He also knows that I am with him and does not want to break his promise to me. Deal will happen!

President Trump on Twitter downplayed the test. "I believe that Kim Jong Un fully recognizes North Korea's great economic potential and will do nothing to disturb or end it," tweeted .
Still, the new rocket seems to be more advanced than some of North Korea's earlier designs. Unlike the long-range missiles of the north, this new short-range missile seems solid, says Hanham. That is, the fuel is already in the rocket before it leaves its fortified shelter. It can start quickly with very little warning, Hanham explains.

If it's an Iskander-like rocket, this new weapon will fly to heights, making it difficult to intercept, said Michael Elleman, a physicist and senior missile defense fellow at the International Institute for Strategic Studies. The Iskander flies at a height of about 30 miles, says Elleman, too high for US Patriot missiles, but too low for THAAD, a system that can intercept long-range missiles.
