How typical that you either overlook or deliberately omitted the key word in my post before rubbishing it. I said that Trump *only* sees the violence. Of course it's appropriate to respond to that with proportionate measures -- sending in the army isn't an appropriate measure and isn't even something he can do anyway, but let's leave that aside.
But it's also what Presidents are supposed to do. Try to solve the problems facing the country. Trump wanted to make America Great Again. Doesn't that involve trying to solve long-standing problems, or was he only ever planning on being a reactive rather than a proactive president?
Put another way, what is the point in dealing with these protests and riots if all that will happen in a few years is that they could end up happening again? The underlying issues of police over-aggression, of the lack of accountability, of the broken relationship between the police and those they are meant to protect, will continue to fester unless somebody tries to do something about it. And, here's the point, I *want* Trump to do something about those problems. Nobody is better of if he fails to do so. Or, rather, when he fails, which is the sad point.
