IDK about that.
Its likely the US has its hands in far more shady, corrupt, immoral dealings, but they are currently the biggest and richest kid on the playground, so of course they are going to get away with much more than a lesser country.
Look at it this way, the US is the only country to have ever used a nuke against another nation in war, so maybe the other nations should feel a little different than they do when the US tests a missile. If the tables were turned its pretty likely the US would use this as an argument too.
