As can be deduced from the definition, it can be clearly observed that this is not a problem in its own as it seeks for efficient use of land in urban development.
It is based on an efficient public transport system and has an urban layout which – according to its advocates – encourages walking and cycling, low energy consumption and reduced pollution
Is there a question we're supposed to answer or was this supposed to be a "fun fact"?
The US is facing the risk of N. Korea developing it's own nulcear Inter Contenential Basslistic misscles (ICBM). Although the US has the largest nuclear arsenal, and imposes many trade sanctions on N. Korea; the N. Koreans still has the capaxity to destroy the USA's allies Japan and S. Korea. Their support can be demonstrated by the thousands of troop in allied countries. Although N. Korea has the nuclear warheads the ICBM technonlgy is not yet complete as they are in phase 3/4 in development.
Also the POTUS's remark on N. Korea could potentialy risk the US's careful balance on N. Korea.
