Compare Ellsberg to Snowden. Obama is worse than Nixon.
Nixon presided over the slaughter that was Vietnam which included the Phoenix program of targeted killings and torture of suspected communists. Phoenix prisoners were subjected to rape, gang rape and they were murdered using some pretty bestial methods that included starvation and pounding dowels through prisoners heads. So even if you factor in drone assassinations and the torture allegation against them neither Obama nor GWB Jr can hold a candle to Nixon.
