Therefore, Moon added the allies are still tasked with preventing North Korea from making any further advancements in its reckless campaign for nuclear and missile weapons and lead to dismantlement.
Michael Elleman, senior fellow for missile defense at the International Institute for Strategic Studies, made the projection in a post on the North Korea analysis website 38 North, based on newly released photos of the Hwasong-15 intercontinental ballistic missile. After it tested two ICBMs in July, Mr Moon said Pyongyang would cross a red line by creating a nuclear-tipped ICBM, and this could risk tougher moves from the United States including military action.
Pyongyang has said its Wednesday missile test was a "breakthrough" and leader Kim Jong Un said the country had "finally realized the great historic cause of completing the state nuclear force".
After initially assessing the missile as a modified version of the Hwasong-14 following Wednesday's launch, South Korea's military now says the Hwasong-15 is considerably larger and potentially capable of carrying bigger payloads.
The drills will mark the first time that six of the stealth fighters fly over South Korea at once, according to the report.
He said South Korea and the US along with the worldwide community have already been applying the most decisive pressure and sanctions on the North.
However, North Korea still needs to prove some technologies - such as re-entry, terminal stage guidance and warhead activation - said Yeo Suk-joo, deputy minister of defense policy at the defense ministry.
"We must prevent a situation in which North Korea misjudges the situation and blackmails us with nuclear weapons or in which the United States contemplates a preemptive strike", Moon said during a full session of the National Security Council (NSC) over which he presided on the day of North Korea's missile test launch.
"For now if there are no sudden changes in situation or external factors, we feel there is a high chance North Korea will refrain from engaging in provocations for a while", said Lee Yoo-jin, the ministry's deputy spokeswoman. North Korea generally tests fewer weapons in the fourth quarter because the temperature drops significantly, putting pressure on fuel supplies, and also troops are required to help with harvests. To do so, the two leaders will continue to apply strong sanctions and pressure to bring the rogue regime to talks. This week's missile launch was the first in 75 days.
"The issue of a naval blockade was never discussed during their phone conversation", a spokesman for President Moon Jae-in told reporters Friday, referring to a lengthy phone call between Moon and U.S. President Donald Trump. "We're seeing dozens of countries engage in different efforts in their bilateral ties with North Korea to cut off both energy, economic ties, and diplomatic ties", Shah said.
