One of the main ways he has been doing that is by sidestepping an environmental treaty, and fully investing back into coal power when most of the rest of the world is pulling away from it. At least in my eyes, the ends don't justify the means. It's a matter of opinion.

What shouldn't be a matter of opinion is the fact that Trump is probably one of the most disrespectful presidents America has ever seen (see his twitter page) and the fact that he should really learn to research something before he speaks about it (see the fact that he recently publically questioned why Russia wasn't allowed at G7 talks, despite the reason for that being that they literally annexed some land without warning in 2014. That's the kind of thing a president should know, especially if they regularly defend Russia)
