Their agenda is deliberately destructive. Look at Tom Hayden and Jane Fonda. As leaders of the anti-war movement during Vietnam, these two individuals know that the fall of Saigon was very much their doing. The North Vietnamese have themselves thanked the anti-war movement for making the takeover of South Vietnam possible. The fall of South Vietnam led to a blood bath in Southeast Asia. In other words, Fonda and Hayden both know that they are complicit in the massacres that the communists perpetrated in South Vietnam, Laos and Cambodia, when those countries fell to communism. So, a generation later, knowing what the American withdrawal from Vietnam led to, both Hayden and Fonda were again pushing for an American withdrawal, this time from Iraq. They knew well what the consequences would be if America had lost and the jihadis had won in Iraq. The surge saved Iraqis from a monstrous Islamic caliphate and cemented the foundation for democracy and a civil society. It avoided a Khmer-Rouge style bloodbath. It scored a victory for U.S. interests and democracy everywhere. No wonder the Left opposed the surge so furiously and hates its success so much.
