One of them is currently supplying and abetting a genocide, kidnapping heads of state, shooting people in the street during gestapo raids, disappearing activists to concentration camps, bombing countries on multiple continents, trying to topple the government of Iran and preparing for multiple invasions.

I know who I consider the bigger threat to peace.
