So there are still people who will say "Martin Luther King is just plain wrong."

Here's a quote from that "plain wrong" speech:

I would like to suggest five concrete things that our government should do immediately to begin the long and difficult process of extricating ourselves from this nightmarish conflict:

1. End all bombing in North and South Vietnam.
2. Declare a unilateral cease-fire in the hope that such action will create the atmosphere for negotiation.
3. Take immediate steps to prevent other battlegrounds in Southeast Asia by curtailing our military buildup in Thailand and our interference in Laos.
4. Realistically accept the fact that the National Liberation Front has substantial support in South Vietnam and must thereby play a role in any meaningful negotiations and in any future Vietnam government.
5. Set a date that we will remove all foreign troops from Vietnam in accordance with the 1954 Geneva agreement.

Part of our ongoing commitment might well express itself in an offer to grant asylum to any Vietnamese who fears for his life under a new regime which included the Liberation Front. Then we must make what reparations we can for the damage we have done.

Now, looking back, if in 1967 they'd done that, wouldn't that have been a far better outcome than what actually happened, after six more years of a disastrous war, in which millions of people of killed and injured, including tens of thousands of young Americans?
