"The US strong protectionism is not through tariffs but through tax incentives, targeted investments hidden as national security contracts and things like "buy american" acts."

what fraction of GDP is that? 1-5%? Europe semi public enterprises have a much bigger weight. Banking, energy, postal services, transport, telecommunications were until recent national monopolies and protecting domestic champions is still a matter of national interest.
