Ted Sorensen, John F. Kennedy's closest adviser,
says
in this article Afghanistan isn't threatening to become another Vietnam.
It already is.
"Even the rhetoric today is familiar—the dire warnings
that an American loss would embolden our enemies and
lead to a “domino effect” chain of setbacks across the
region; that we must keep on sending fresh troops to
kill or be killed, thereby expanding both America’s
mission and stakes, even though Obama had no more
initiated America’s role in Afghanistan than Kennedy
initiated America’s role in South Vietnam. There was
little the U.S. could do to stop the flow of arms and
enemy combatants into South Vietnam across its porous
border with North Vietnam, just as there is little the
U.S. can do now to stem the flow of arms and enemy
combatants pouring across Afghanistan’s porous border
with Pakistan."
