I don't see any sauce to the headline assertions, but that's life with the internet.

After doing a search, I asked Brave AI about it. Here's the reply:

There is no evidence in the provided search results confirming that The New York Times or Politico reported on February 20 that Russian intelligence delivered a fully developed US strike plan to Tehran.

The available sources discuss heightened tensions, US military preparations, and diplomatic efforts regarding a potential US strike on Iran, but none mention Russian intelligence sharing a US strike plan with Iran. Some reports note strategic mistrust between Russia and Iran, including Russia's refusal to transfer advanced weapons systems to Iran and Iran's unwillingness to send troops to support Russia in Ukraine.

Therefore, based on the provided context, the claim appears unsubstantiated.

So, some or all of this might be true. Or not. There's quite a bit more to the two posts below than Russia leaking America's war plans to Iran, btw. Worth reading through.
