That depends on a lot of things, including perspective. Things can be legal according to one set of rules, yet illegal under another set. EU member states certainly could see this as illegal interference in their economies and a stretch of US jurisdiction. There is also a good chance that this goes counter to at least a few international trade agreements. Agreements the US still desperately needs for other things it wants to keep doing. It appears a very short sighted policy, by people who probably don't give a shit about whatever damage they do long term. Once they are out of office, it is no longer their problem. If it made them richer, they won. It's the ordinary people that will likely pay a price for this at some point, but not them.
