It's a shame the Russian ambassador didn't repay the courtesy of listening to the US remarks. Not every claim will be responded to as the Russian colleague is adept at drowning others with a tsunami of misinformation, but he did say something right — the indivisibility of security. However, it cannot be a one-way street for Russia at Ukraine's expense.
While Russia still values the OSCE, as it is the remaining pan-European forum on security where Russia can have input, the US under the current administration sought to bury the memory of the Afghan withdrawal by finding a new enemy it can provoke. While Russia still prefers to settle this conflict peacefully, its position has been made clear should the US continue to escalate.
