How strong is US-Ukraine wartime alliance? What the leaks reveal.

The extraordinary cache of recent and highly sensitive U.S. intelligence documents that have appeared these last weeks on social media sites and gaming chatrooms – largely focused on military and diplomatic aspects of the war in Ukraine – includes revelations on friend and foe alike.

In the “foe” column, the leaks include precise and timely details of Russian war planning and suggest deep U.S. penetration into Russian decision-making centers, from the Kremlin to the mercenary Wagner Group.

But then there are the friends – and in particular, Ukraine.

The documents – about 100 pages of what appear to be photocopied (and sometimes altered) intelligence briefings and “secret” reports – also offer a window into the U.S.-Ukraine relationship that has been forged by more than a year of war.
