I would like to point out that the food blockade as a war crime only happened AFTER WW2 ended. During WW2 it was perfectly legal.FDR was not going to charge anyone from Britain with any crime. The US looked the other way on election interference and on assassinations carried out on US soil according to Intrepid.
Food blockades constitute a war crime. See famine (starvation) of civilians (API Art. 54, APII Art. 14, Rule 53)
Also the Statute of the International Criminal Court establishes that starvation of civilians constitutes a war crime when committed in international armed conflicts.
As for the other issues I would like to point out the articles about the election stuff straight up say the US government didn't know anything about it. Also I'm like 90% certain most of it was debunked anyway. Also the assassinations on US soil I know are a conspiracy theory.
