While not a traditional conflict zone, the extreme risk of arbitrary arrest and long-term detention for foreigners, often for actions not considered crimes elsewhere or for vaguely defined "espionage," is a primary driver of "Do Not Travel" advisories. The opaque legal system offers no due process. Furthermore, the volatile geopolitical situation means regional tensions can escalate without warning. Any visit, typically only possible via highly restrictive state-controlled tours, carries profound personal risks and ethical considerations.
