“fwiw...I’m hearing that the OSCE cleared out of Mariupol in a hurry and left behind A LOT of documentation that never made it into their official reports.”
No surprise, literally EVERY Leftist operation had their fingers in Ukraine, which is also why many here support them.
The Organization for Security and Cooperation in Europe (OSCE) is billed as a preeminent international group which can be relied on to observe and report impartially on things like elections, border disputes, ceasefires, etc.
The fact OSCE was caught acting as a defacto spy agency for one side in Ukraine renders it useless as a neutral arbiter going forward, and confirms the worst suspicions Russia has had about the organization for years.
