No because treason is defined in out Constitution. While laws against sedition come and go, treason (aid and comfort to the enemy in wartime) has never been “repealed” from the Constitution.
Just because Jimmy Carter was unwilling to prosecute the traitors who betrayed American in Vietnam in support of the North Vietnamese Communists (Jane Fonda, the Weather Underground, the Yippies, and others who conspired to stage riots in the streets, burn armories, pledge support to the Viet Cong, assassinate police and congressmen...), does not mean that the crime has become meaningless.
We had traitors in this war too. Nadil Hassan at Ft. Hood was a traitor and he was enabled by a fifth column in our US military who empowered him in the name of political correctness even though they KNEW he was communicating with Al Qaeda and making jihadist death threats against non-muslims.
