With the current situation in the USA, I had a look at the wording of the Oath of Office the US president takes, and was surprised to see that the oath is to "preserve, protect and defend the Constitution".
Why is the oath worded to the constitution, and not the people of the USA?
From Comments and additional Context for future readers: From @vsz :
Just for context, there have been several leaders (Stalin, Hitler) who based their rule on preserving, protecting, and defending the people (or claiming to), completely disregarding any constitutions and other laws their countries had before.
The current German oath is worded (taking into account people AND law):
I swear that I will dedicate my efforts to the well-being of the German people, promote their welfare, protect them from harm, uphold and defend the Basic Law and the laws of the Federation, perform my duties conscientiously, and do justice to all. So help me God. (Translation from Wikipedia)
That contrast was what actually lead me by being surprised by the lack of "people" in the US-Oath.
Hitler actually had an oath on people AND law as well. There is only so much an oath can actually hold you to!
I am not familiar enough with Russian history to know if Stalin found a loophole or just disregarded his oath, too!
