No one who understood what Trump is believed him. You shouldn't have either.

I think that's overly pessimistic most (?all) politicians betray voters but seeing shades of grey or bright sides isn't a bad thing.

Lol. You're not in the US so I'll forgive your ignorance. Trump has managed to make himself an exception to any rules about looking for the bright side. If he appears to give you a reason for optimism, wait for him to reveal the novel way he'll ruin it. Between his corruption, his desire for power and status, and his raw stupidity, he poisons everything he touches.

I'm looking for the bright side, believe me. A couple times I thought I might have seen one. You know, like you did with your hope that he wouldn't start any wars. But the pessimistic view keeps making all the correct predictions.
