That less propaganda that Jim has requested sure would be nice.
Firstly, a declaration(s) is NOT a security agreement between the US and UKR. It is merely that, a declaration by one political arm of this government's UNAPPROVED political policy (i.e., approved by the US Senate). We have no officially endorsed, binding commitments with UKR, by treaty or statute. Additionally, UKR was never part of NATO, nor was (or is) an officially NATO-endorsed aspirant.
IMO, the article is just more UKR support propaganda fodder.
[Lastly, and this is just picky. BILATERAL means between TWO parties. Declarations by the G7 (SEVEN), no matter what import they carry (or do not), are not that. Who writes this stuff?]
