Assuming that Israel & Zionists are behind every evil in the world is a modern rendition of Hitler’s anti-Semitic claim that Jewish bankers run the world. Zionism is a rightwing colonial ideology & so of course its proponents are involved in political intrigues of all kinds around the world. In the US, they have long been involved in eugenics, anti-immigration organizations, pro-war actions. That’s what rightwing activists do. But ISIS, the Taliban, Al-Qaeda, nor certainly the US Congress do not need Zionists or Israel to engage in nefarious actions at the expense of humanity. They can create hell well enough on their own.
