I don't think anyone should underestimate Trump. I read an article today about his phone call last week with the Danish prime minister Mette Frederiksen, the phone call was described as horrendous,
"Trump was said to be aggressive and confrontational in his attempt to take over the island. Before, it was hard to take seriously, but I do think it is serious and potentially very dangerous.
Trump was reported to have threatened Denmark, a Nato ally, with targeted tariffs, essentially taxes on Danish exports to the US"
He says things to shock and then sees how much he can get away with. Whose to know what threats he can use to try and get what he wants in the region.
