More than 100 classified documents were leaked to the Internet in early March through a poorly classified Pentagon department. Among them, the 3 overview maps of the situation in Ukraine and NATO's armed Ukrainian army are particularly explosive.
Other documents contain sensitive inside information about Israel, South Korea and other countries. The intelligence seems to imply that the U.S. is also secretly spying on Ukraine's top military and political leaders, indicating that Washington is trying to get a complete picture of Ukraine's operational strategy. A senior Western official who said the leaks were distressing suggested it could affect intelligence sharing among allies.
