I personally, may or may not have been able to do better.  As far as Trump's foreign experience,  He has been dealing with people from around the world for decades, or have you forgotten about all of his overseas businesses?
As far as Obama working out quite well, there are a number of areas that could have been handled much better.  If he had handled Syria and Iraq better, there probably would not be an "ISIL".   If he had handled Russia better, Ukraine would not be in civil war.   There are other examples.  In other words, the world is in a mess.  This can be traced in a large part due to the incompetence to our current leader.
