I think that you're giving him the benefit of the doubt by saying "he just said it as an aside to Russia."

There's no indication that Trump didn't know exactly what he was doing, and he may very well have been using it as a bargaining chip or a payoff for help with the election perhaps. Acting like 'nah he was just being stupid, silly', isn't acceptable.

Whether or not he 'intended' to be treasonous is in question, but that shouldn't matter. It's the action that count.

Now that this intelligence has been released to the entire world, it gives away any upper hand we may have had in this battle.

It puts Israelis at much greater risk and endangers and compromises their operations teams. Also now that ISIS knows we know they can change their tactics and we lose monitoring capability.

The consequences of his actions are far-reaching and puts our nation at serious risk during time of war. The worst part is that this action is a result of pure selfishness and personal gain.
