A  Belgian political consultant, Kerknawi, suggested there was little Trump could do during his 29 hours in Brussels to improve his reputation.

"He's very unpopular in Europe," he added. "People don't think he's very intelligent. Brussels is a complex city and European society is different from American society and he doesn't seem to get it." 

While there was little the Trumpster could do to improve his reputation, there was still room for him to tank his reputation further, and the Trumpster managed to find a way.
