European leaders may welcome a strong showing by Democrats in the U.S. midterm elections, but a change in congressional control is unlikely to bring immediate relief, according to the source article.
Congress has limited ability to constrain presidents on foreign policy. As a result, even if Democrats take over, Trump could still focus on international affairs and trade, areas where the executive branch faces relatively few congressional checks.
That leaves Europe exposed to the possibility of fresh disputes and tougher demands from the U.S. administration.
