And if it wasn't called treason when jane fonda went to N. Vietnam and gave aid and comfort to the enemy.
And if it wasn't called treason when Jon Carry denounced America and falsely accused American Troops of all forms types of atrocities giving Ho Chi Minh a victory he could have never achieved otherwise, thereby giving aid and comfort to the enemy. 
And if it wasn't called treason when Nazi Pelousy and Co met with Asshead as he was supplying aid and comfort to the enemies of Iraq and Coalition Troops 
And if it wasn't called treason when Jay Rockefeller took a trip by himself in January of 2002 to Saudi Arabia, Jordan and Syria, and told each of the heads of state that it was his view that [President] George Bush had already made up his mind to go to war against Iraq 
When will giving aid and comfort to the enemy ever be called treason, and dealt with accordingly?
After all the events mentioned above, my guess would be NEVER!
