Analysis Was massive US bomb dropped on Afghanistan the mother of all warnings to North Korea?

When he was running for president, Donald Trump famously vowed to “bomb the s---” out of the Islamic State. Despite a recent series of reversals on other foreign policy issues, he appeared to make good on that promise Thursday.
At 7.30pm local time in Afghanistan, the US military dropped the most powerful non-nuclear bomb in its arsenal on a compound of Islamic State tunnels and caves in Nangarhar Province in Afghanistan, near the Pakistani border.
The GBU-43/B Massive Ordnance Air Blast, also known as the “mother of all bombs,” had never been used in combat before.
Even though President Trump didn’t specifically authorise dropping of the 11-tonne bomb, he may still get a political boost from it.
And even though its use may not have been intended as a message to another troublesome nation, North Korea, it may send one - a reminder that the US is prepared to use some of the most powerful tools at its disposal should the need permit.
