Does Trump's chaotic political style work?

Since he was first sworn in, US President Donald Trump has caused a stir on an almost daily basis with new announcements of extreme measures in politics and the economy. Many of them - including major tariff hikes - have been cancelled or postponed a few days after being announced. Others, such as mass redundancies or deportations, have been put on hold by the courts. Europe's press takes stock of this erratic style of government.
