When we talk about liberalism today, we aren't talking about classical liberalism the way you're referring to. We're referring to leftism which supports islamists unconditioinally, wants to erase Israel, wants to enforce marxism, wants to sanction India, Israel and any other country standing up for itself, wants to label every conservative as a Nazi, supports the leftist takeover of universities, etc.
Jews, particularly the media organizations, for the past 30 years have supported this type of leftism calling itself liberalism, which is what have given hamas supporters and other islamists so much space and media cover. What muslims do in the west today would be impossible without leftist institutional support. Now the rich jews realize that this will always come to bite them back. They are certainly not safe anymore in Europe, ironically.
