Ironically Russia was the only country to vote no in 2023 on the U.S. General Assembly adoption of the (1997) Convention on the Prohibition of the Use, Stockpiling, Production, and Transfer of Anti-Personnel Mines and on Their Destruction (the "Ottawa Convention"). Ukraine voted yes, and the U.S. abstained.
Also, neither the U.S. nor Russia are direct parties to the Ottawa Convention, but Ukraine is. In 2016, as a response to Russia annexing Crimea, Ukraine implied that if anti-personnel land mines were used in Crimea or Donbass that it was totally Russia doing it and not Urkaine, and/or (gotta love passive legalese shit all over the place—whatever) admitted it might commit war crimes by violating the convention ("The application and implementation by Ukraine of the obligations under the above Convention, as applied to the aforementioned occupied and uncontrolled territory of Ukraine, is limited and is not guaranteed."). Then in 2018 it claimed it had been "finding" such mines but it was all on Russia ("Shortly after the commencement of the military confrontation Ukraine started to discover on the liberated territories the mined areas containing anti-personnel mines, originated from the State, which is non State party to the Ottawa Convention. Ukraine has been regularly reflecting such facts in its annual declarations since 2015.").
TeCHniCaLLy (
), I guess Genocide Joe isn't telegraphing his commission of war crimes here, because the U.S. rarely agrees to legally "take options off the table". But this is undeniably the U.S. openly encouraging Ukraine to commit (more) war crimes, because Ukraine is a party.
