I think PTrump will perform better in other aspects than PObama but he will not get to the level of respect PObama gained during his term.
Right now, the Americans badly need a president who will perform, and not someone who is good only for showoff. That should be the case, even if it means alienating some of the most trusted allies.
Americans can do without allies? America has gained its allies for many years, and you can lose a few days. If country is not your ally, is a potential enemy. You seriously think that without allies America can be great?
