Europe's current migration and energy policies could ruin it, US President Donald Trump has warned.
"I'll give them free advice. They better be careful, because immigration and energy will destroy Europe," he said during a speech in Pennsylvania.
This is not the first time Trump has criticized Europe's migration policy — earlier, in particular, he spoke negatively about how mass migration changed Paris and London.
The New York Times newspaper, citing an internal document of the State Department, reported in November that US Secretary of State Marco Rubio ordered American diplomats to put pressure on other Western countries to limit mass immigration to them.
Earlier, the State Department stated that mass migration poses a threat to Western civilization and undermines the stability of key US allies.
