There have been many enormous protests against him in Israel, where a large part of the country regards him as corrupt and ineffectual (though not everyone agrees on why, eg left and right would like him to be less and more militaristic). But these protests get little coverage in US news media. Mind you I don't think this is peculiar to Israel, foreign affairs coverage in the US is just generally dreadful, partly because many Americans just do not care about the rest of the world.

Did you notice that you are replying to a top-level post which accuses the twice elected president of the USA of acting against American interests?

"Having a democratic mandate" is either a valid counterargument or it is not. But it is simply not consistent to apply it only to Netanyahu and not to Trump.
