Why do you consider him a role model? Based on how he spoke instead of the actions he took? Most politicians, put on a facade. They play the crowd, kiss the babies, etc. They change their positions with whatever way the polls go. What good is a smile and manners if someone is robbing you when you're not looking?
Bush started an entire war on a completely fabricated lie. And Obama carried the torch, despite running originally against the Iraq war! Maybe you don't feel the consequences of this because you don't have to pay the bill and your family members were never deployed to a war zone.
Trump, for all his flaws, his instincts are for negotiation and peace. He just negotiated a peace deal between Rwanda and Congo:

And again between Azerbaijan and Armenia: https://www.bbc.com/news/articles/c39dzl1lzrgo
He also seemed to handle the Iran-Israel conflict in a way that for befuddling reasons to me, actually deescalated the situation, despite the controversy at the time.
I'll take mean tweets and strong negotiation over smiling faces and reckless invasions any day of the week.
