"real action" on China would require the hard work of making the case to the 100m American TT users, building a bipartisan consensus, and passing a bill.
The current administration has no intention of doing any of that. Attemping to rule by decree is easier and makes for immediate headlines. By the time the executive order gets thrown out in court, plenty of political hay has been made among the party faithful.
And when the order does get thrown out in court, the administration blames 'activist judges' instead of the merits of their own case.
