Its seems likely that it was for these heavy accusations of genocide against the U.S. government and his calling attention to the cruel indifference of Americans and blind immorality of the U.S. establishment that King was silenced, and not because of his civil rights crusade.
Let us read some of the powerful and vehement anti war and anti U.S. government pronouncements from his Beyond Vietnam speech of April '67, which was headlined in bold print the next day by newspapers around the world. King spoke first of the "betrayal of my own silences" [re the war] in previous years:
"Over the past two years, as I have moved to break the betrayal of my own silences and to speak from the burnings of my own heart, as I have called for radical departures from the destruction of Vietnam, many persons have questioned me about the wisdom of my path. At the heart of their concerns this query has often loomed large and loud: Why are you speaking about war, Dr. King? Why are you joining the voices of dissent? Peace and civil rights don't mix, they say. Aren't you hurting the cause of your people, they ask? ...
There is at the outset a very obvious and almost facile connection between the war in Vietnam and the struggle I, and others, have been waging in America. A few years ago there was a shining moment in that struggle. It seemed as if there was a real promise of hope for the poor -- both black and white -- through the poverty program. There were experiments, hopes, new beginnings. Then came the buildup in Vietnam and I watched the program broken and eviscerated as if it were some idle political plaything of a society gone mad on war, and I knew that America would never invest the necessary funds or energies in rehabilitation of its poor so long as adventures like Vietnam continued to draw men and skills and money like some demonic destructive suction tube. So I was increasingly compelled to see the war as an enemy of the poor and to attack it as such.
Our government felt then that the Vietnamese people were not "ready" for independence, and we again fell victim to the deadly Western arrogance that has poisoned the international atmosphere for so long. With that tragic decision we rejected a revolutionary government seeking self-determination, ... by clearly indigenous forces that included some Communists. For the peasants this new government meant real land reform, one of the most important needs in their lives.
For nine years following 1945 we denied the people of Vietnam the right of independence. For nine years we vigorously supported the French in their abortive effort to recolonize Vietnam.
Before the end of the war we were meeting eighty percent of the French war costs. Even before the French were defeated at Dien Bien Phu, they began to despair of the reckless action, but we did not. We encouraged them with our huge financial and military supplies to continue the war even after they had lost the will. Soon we would be paying almost the full costs of this tragic attempt at recolonization.
After the French were defeated it looked as if independence and land reform would come again through the Geneva agreements. But instead there came the United States, determined that Ho should not unify the temporarily divided nation, and the peasants watched again as we supported one of the most vicious modern dictators -- our chosen man, Premier Diem. The peasants watched and cringed as Diem ruthlessly routed out all opposition, supported their extortionist landlords and refused even to discuss reunification with the north. The peasants watched as all this was presided over by U.S. influence and then by increasing numbers of U.S. troops who came to help quell the insurgency that Diem's methods had aroused. When Diem was overthrown they may have been happy, but the long line of military dictatorships seemed to offer no real change -- especially in terms of their need for land and peace.
The only change came from America as we increased our troop commitments in support of governments which were singularly corrupt, inept and without popular support. All the while the people read our leaflets and received regular promises of peace and democracy -- and land reform. Now they languish under our bombs and consider us -- not their fellow Vietnamese --the real enemy. They move sadly and apathetically as we herd them off the land of their fathers into concentration camps where minimal social needs are rarely met. They know they must move or be destroyed by our bombs. So they go -- primarily women and children and the aged.
They watch as we poison their water, as we kill a million acres of their crops. They must weep as the bulldozers roar through their areas preparing to destroy the precious trees. They wander into the hospitals, with at least twenty casualties from American firepower for one "Vietcong"-inflicted injury. So far we may have killed a million of them -- mostly children. They wander into the towns and see thousands of the children, homeless, without clothes, running in packs on the streets like animals. They see the children, degraded by our soldiers as they beg for food. They see the children selling their sisters to our soldiers, soliciting for their mothers.
We have destroyed their two most cherished institutions: the family and the village. We have destroyed their land and their crops. We have cooperated in the crushing of the nation's only non-Communist revolutionary political force -- the unified Buddhist church. We have supported the enemies of the peasants of Saigon. We have corrupted their women and children and killed their men. What liberators?
Now there is little left to build on -- save bitterness. Soon the only solid physical foundations remaining will be found at our military bases and in the concrete of the concentration camps we call fortified hamlets. The peasants may well wonder if we plan to build our new Vietnam on such grounds as these? Could we blame them for such thoughts? We must speak for them and raise the questions they cannot raise. These too are our brothers.
