I guess politics is a Rohrschach test so I guess I see the same facts differently because I am coming at it from a different perspective. Some of the things you mention, increase in deportations and hating on allies were things that Obama did too (only different allies), although I agree that you can't compare Obama and Trump as to form or style or presidential temperament, and understand your embarrassment from the current administration that has handled many issues in at best, a clumsy and inept manner unfit for the reputation of the US. I fully support pulling out of the Iran deal and didn't approve the Obama administration handing the regime huge suitcases of cash which they likely put right into the hands of Hezbollah, and the Assad regime (it's horrible to think we helped them buy their chemical weapons
). As for dissing our allies on that treaty, our allies (the Europeans) just want to make economic deals with Iran to support their faltering economies, without considering the potential security cost. Given the state of the Iranian economy and internal dissent, I think this is a good time to re-institute sanctions with the goal of renegotiating a better deal, or God willing, seeing regime change (a long shot, I know). As for upsetting the "balance of power" in the Mideast, the balance has changed tremendously with surprising allies such as Israel and Saudi Arabia and some of the gulf states, given the increasing threat posed by Iran.
One aspect that no one seems to mention is that the economy has flourished under Trump so far (and for better of worse, each president gets "credit" for the economy on his watch). For example, African American unemployment is the lowest it has been in a generation. I consider the right to a job to be a fundamental human right and prefer a system with increased opportunities from the private sector than government mandated transfers of wealth, which seems to be the preferred method under Democratic presidents.
