I suspect the primary reason we (in the USA) are focusing so much on it is that these are the people appointed, promoted, funded, etc., by people we elected. Some people think that has meaning while many are cynical enough to think that they're all the same under the various masks.
This is a revelation for most people, especially younger people, and they're dealing with the immediate, personal, consequences.
As with the embarrassment created by the second Bush administration, whereby we squandered a great deal of global goodwill after 9/11, we've done a stellar job of undoing the redemption we thought we had gained by electing Obama in 2008.
Many Americans really thought we could be less embarrassed of our leadership with that decision.
The story is still unfolding. Our government will be measured by how it acts out the next few months and how it responds to the inevitable criticism from the rest of the world. As Americans, we will be measured by how we respond to our government.
