The fact that Israel is a nation propped up by $3.5 billion of arms spending by the US, yet makes sure to oppress the Palestinian population in their country in the guise of maintaining their "Jewish mess" is a direct affront to your "western values in alliances" nonsense.
Alliances are based out of pragmatism and a common enemy/threat. They have always been the case since history, whether it was the aggressive Assyrians' neighbours against them, to the Franco-Ottoman alliance, to the Axis alliance in WW1.
