treasonous
Disloyal to state
Treasonous describes acts or intentions that betray one's country or sovereign—the adjective form of treason.
A treasonous plot aims to overthrow the government; treasonous correspondence with an enemy power could get you executed.
The word extends loosely to any serious betrayal: His treasonous departure to a rival firm took half the clients with him.
