That’s a straight up lie and you know it. 8 million in 4 years is a tidal wave no matter how you slice it.
Source? There are not even 8 million refugees in all of the EU together. The total refugee population is around 7 million in the entire EU.
And even if they would have all arrived in the last 4 years (which they didn’t, less than half did & mostly from Ukraine), that “tidal wave” of around 1.5% of the total population sure is massive /s
Edit: The 8 million “immigrants” figure for the US is fake news as well.
