Well, technically you are correct that you can, but maybe it is unwise...
...to do what you voted them in to do...
Hmm, can't so much remember any governments who fully did what the electorate voted them in to do, although some had better excuses than others. Some had effectively no worthwhile excuse and some were in a situation unanticipated at the time of election or promised, intentionally or otherwise, things that were ambiguous. And some only had a choice between bad options and the least worst was all that they could do, and they don't get much credit for that.
...to protect your nation from inside and out...
To protect their own arses, more like. Not sure about the 'inside and out' bit, though. I'll admit though, rather like football referees, sometimes we have expectations that probably won't be met by normal human beings. We have just made the job too difficult, but that doesn't excuse a lot of the worst things that politicos do.
I can't honestly say that I share your faith in the general niceness of politicians, and any that are nice tend to be sidelined by the system. But it is good that someone has that unsullied point of view, rather than us all being cynical and disillusioned.
