Half of Europe would be considered “far left” from a US perspective. Affordable housing? Universal healthcare? Parental leave for long durations? Walkable cities and public transit? Try getting any of those to fly with the US neoliberals.

Considered != is. Most of Europe has social democrat / labour parties which are left leaning democratic parties and committed to democratic principles. They're not far left by any stretch regardless of what anyone in America thinks. But Eastern Europe has certainly suffered the experience of far left governments in the past and has no desire to go back.
