That’s the verdict of co-founder of The Intercept Jeremy Scahill, who looked back into U.S. President Joe Biden’s political career and identified the key moments where he defended Israel’s alleged war crimes, from back in the 1980s to present day.

Biden has been in public office for 50 years, and during that time he has been one of Israel’s biggest defenders, even when the country has killed civilians.

Scahill argues that U.S. weapons and money have enabled Israel’s attacks on Gaza and that the more than 4,700 children killed “should be a permanent stain” on Biden’s legacy.
