Both strayed far off from the ideals they originally strived for.
Israel went from a refuge for Jews after the Holocaust to Jews committing genocide against another group of people. The USA went from fighting against kings and authoritarianism to fully embracing it.
Both believe in colonialism and forceful removal of existing populations.
Both exploited a terrible tragedy to increase violence against those they believed to be responsible: Israel with 10/7 and the USA with 9/11.
Both lack true separation of church and state; Israel is dominated by Zionists and the USA by Christian evangelicals.
Both kill children in schools; Israel with drone strikes and the USA with school shootings.
Both are obsessed with "national security" and fear of outside influence.
Any others I might've forgotten?
This is not a shower thought
