It sounds like all he wanted was formal written security guarantees in exchange for mineral rights, and it was like $500 billion in mineral rights. All Trump could do though is praise Putin & say trust us bro. Zelensky is smart enough to know the terms of such agreements needs to be in writing & not just “trust us bro.”
It absolutely would make a difference. Those terms lay out conditions on what happens if one side breaks the agreement & can include things like freezing assets, escrow accounts, sanctions, etc.
Now in terms of the obligations of NATO to members those still exist. But I’m unaware of any obligation by the US to stay a NATO member.
