OK, so I think the nations surveyed are biased, but I have now seen two polls with roughly similar polls.
So Pew, with a larger base and solid credibility has that among foreign nations polls in their nations data set showed an improvement in favorability rating for the POTUS have gone from 17% to 75% give or take a few percents. OTOH, the attitude towards the US among whichever nations Pew polled had the attitude towards the US only rising from 34% to 62%. Most commentary has this as foreigners now fear that either Trump himself or some clone of his might well become POTUs in the not too far distant future.
In the meantime, I wish the best to the current POTUS on his current trip abroad.
