WASHINGTON, July 5. /TASS/. European nations are starting to learn how the transformation into a third-world country takes place because of the migration policy, US President Donald Trump said.

"Europe is learning that when you take in Third World criminals, you become a Third World Country. It happens quickly, in just a blink of the eye. I was elected just in time," the US leader wrote on Truth Social.

Trump repeatedly criticized European allies of Washington for too soft migration policy.
