48. That doesn't matter and it has no requirement for war

From M-W:

The system of separating the various senses of a word by numerals and letters is a lexical convenience. It reflects something of their semantic relationship, but it does not evaluate senses or set up a hierarchy of importance among them.

Either definition is completely acceptable. One is not more valid than the other. There is no word "treasonist" in the dictionary because we have the word traitor.

I don't have to write a sentence that says: "Donald Trump is a traitor to this nation - I mean he committed treason." I simply need to say "Donald Trump is a traitor." When we speak of traitors, the name Benedict Arnold often comes up. Why? Because he committed treason. Yes, we were at war at the time, but that is not a requirement for treason.

Your stated definition of treason is incorrect. The mention of a time of war is no where to be found in the definition in either the dictionary or US Federal Code. I believe the acts of Donald The Chosen are much more in line with the federal definition of treason below, clearly fit the term treason, and therefore, he is a traitor. If there were a word "treasonist" he would fit the likely definition of that word as well.

Finally, war is not required as part of the Federal definition of treason.:
