This is just a nonsense word salad of excuse making. And you're terrible at it and should quit.
"Declassification diplomacy" refers to declassifying past misdeeds in order to curry favor in the present day. Like declassifying our support for a regime in Latin America during the Cold War.
What happened was that the US was informed by an ally of something highly sensitive that _it_ had gathered. And Trump felt the need to share it with the Russians. Without asking the provider country first.
Who gave us the right? It's not our intelligence. It was shared with us on the condition we don't share it.
Why should they ever share with us again?
Your excuse is such bullshit, I'm actually embarrassed for you.
