North Korea's Kim Jong Un and daughter inspect military spy satellite ahead of launch.

The US State Department has warned North Korea that it will use "a number of tools" to hold the country accountable if it proceeds with an illicit satellite launch using banned long-range missile technology. The launch would violate multiple UN Security Council resolutions. North Korean leader Kim Jong Un has reportedly completed a military spy satellite this week, which he argues is necessary for space-based reconnaissance and countering the US and South Korea. The State Department has promised to crack down on North Korea if necessary, using a range of tools at its disposal.
