I don’t see an Open Borders policy in any of those links. Most of them are about how the countries are tightening their rules for allowing migrants. You cannot tighten rules unless they already exist, they wouldn’t exist if the policy was Open Borders.

Invoking “socialists” over-and-over doesn’t prove anything about Open Borders and kind of undercuts your point. There’s also no mention of right-wing leaders like Ronald Reagan or George Bush. They both pushed policies that increase immigration and asylum seekers.
