The Treason Clause refers to “enemies,” not foreign nations generally. And “enemy” has been the subject of over six hundred years of consistent judicial interpretation (the phrase goes back to the English Statute of Treasons of 1351). For a foreign nation to be an enemy, we must be in a state of declared or open war with that nation.

As we are not in declared or open war with Russia, it doesn't fall under the definition of treason. If "an adversary" would rise to the level of "enemy" then that would allow the state to broadly interpret the law to encompass plenty of actions as treason, as "aid and comfort" is so vague. And this is the opposite of the intent of the founding fathers, as they specifically define it to both show how important it is and to stop the abuse of it by the state, which they had seen plenty of times.
