They aren't trying to force "social security" on us, it's an article primarily aimed at an American audience using the term Americans will be familiar with in the headline. The article body calls it the Department for Work and Pensions

Imagine being from the UK and complaining about someone else "forcing" anything on you. Lmao.

Dress up like a yeehad and throw some Baja blast in a harbor. That'll raise some suspicion.

Social security is and has been a thing outside of US.

In particular, it seems to be something in the UK https://www.gov.uk/government/organisations/department-of-social-security

So besides the mix of Britain and the UK, the rest is plain wrong.

Social security is a straight translation of Sécurité Sociale that we use in France
