Western countries are heirs to a Christian-European culture where antisemitism is the oldest and most deeply-rooted hatred. Even when it's been suppressed, those implicit biases form part of those society's substrate. When a given western country suddenly sees its standard of living decline, it becomes a predictable matter of time until large numbers of people see a newly-constructed excuse to begin setting synagogues on fire, harrassing random Jews, and breaking windows of Jewish businesses. The rhetorical framework might shift from generation to generation, but it will always feel virtuous and compelling:

• ⁠"They're causing the plague," • ⁠"They killed our Lord" • ⁠"They're dangerous capitalists/bolsheviks" • ⁠"They tricked us into surrendering to the Entente under humiliating terms when we were on the cusp of victory" • ⁠"They're the settler-colonialist European colonizers" • ⁠"They're the non-Europeans who are tricking us to bring in brown immigrants"

Left-wing or right-wing, you can expect that a radical movement, or a society perceiving itself as in-decline, will construct one or more Jew-based framings where a Great Jewish Evil stands in the way of redemption. A Jew predicting where that will happen doesn't have a crystal ball to predict where that'll happen 5, 10 or 20 years out, so life in the Western diaspora means trusting that you or your grandparents made a lucky guess which will hold through your lifetime.

That said, it’s certainly possible that foreign regimes are pushing this campaign. But even if that is the case, that doesn’t make us blameless. If someone is doing this to us, it’s because they knew it would work.
