If it is such a big deal to Europe they should have listened to Trump when he said take the prisoners coming from you country. They didn’t, they thought he didn’t mean it. Apparently he did. Maybe next time they’ll take him more seriously
Best observation from 2016, in my opinion, was by Salena Zito (I paraphrase): "Trump's opponents take everything he says literally, but they don't take the man seriously. Trump's supporters, on the other hand, don't take his words literally, but they do take the man seriously."
He talks the way he talks. But he means business. He should always be taken seriously.
