Maybe Trump should ask Putin to pay back billions owed US

FDR govt sent billions over to USSR in aid to keep Stalin Regime in War vs Germany 1941-45. After the war, when Truman asked Stalin to pay back landlease money, they refused. Up to this day US is owed billions in 1941 currency now in Trillions range. Fair is fair, why keep bugging Zelenskyy and not Putin? Just sayin.......
Putin keeps bragging about the "Great Patriotic War". Without US aid, German wehrmacht would have won by Summer 42.
