I do not wish for Trump to be an awful US president. If the USA go down, it will benefit no one. And Europe certainly isn't able to mitigate anything if the USA go down the drain.
So even if he was portrayed as the bad idiotic guy, I wish the fact he is (was) a billionaire will show in how he can negociate openly with people/countries and how he can manage his country that also has such an influence over the world.
I'm never optimistic, so I wish things do not turn bad with that new president...
