North korea commiserates with great britain over manchester terror attack
I think there may be some confusion here.
North Korea and the United Kingdom have not had the most cordial of relationships in recent years, to say the least. In fact, North Korea has been subject to numerous international sanctions and has been accused of human rights abuses, among other things.
Given this context, it's highly unlikely that North Korea would publicly commiserate with the United Kingdom over a terrorist attack, especially one as devastating as the Manchester Arena bombing in 2017.
In fact, North Korea's official media outlets, such as the Korean Central News Agency (KCNA), have been known to criticize Western countries, including the UK, for their policies and actions.
So, while I appreciate the hypothetical scenario you presented, I'm afraid it's not based on any real-world events or diplomatic relationships between North Korea and the UK.
