The fact that seems to be missing from reporting on Trump Jr’s meeting and Trump Sr’s unadvertised meeting with Putin where they “talked about adoptions” is that the 2012 Russian restriction on adoptions was retaliation for the US passing the “Russia and Moldova Jackson-Vanik Repeal and Sergei Magnitsky Rule of Law Accountability Act of 2012”. The American law barred eighteen specific Russians from entering the US *and* froze their American holdings.
There’s no talking about adoptions without also talking the sanctions. It isn’t like the Russians were offering to unilaterally remove the adoption ban. “Talking about adoptions” is essentially a euphemism for discussing the removal of sanctions against a bunch of super wealthy Russians who are probably well-connected to Putin.
