Odd Afrikaner act by trump

Recently trump made an odd executive order on the Afrikaners of South Africa seen below https://www.whitehouse.gov/presidential-actions/2025/02/addressing-egregious-actions-of-the-republic-of-south-africa/

This is illegal and done simply in retaliation for South Africa backing Palestine, Also Afrikaners are indigenous to the Netherlands and Germany and trump has not consulted and has angered those countries by this act.
