Washington can now see in the starkest relief the basic immorality of the Carter administration. It is, incredibly, an immorality that is quite willing to sell out millions of black people in the name of expediency, that claims self-righteously to talk about majority rule when it really means black power, and that particularly fools itself about its grand moral postures.

I am referring to the "forward-looking and positive" policy toward Africa that Secretary of State Cyrus Vance recently outlined. In one more (I have lost count because I do not have a computer) "restatement of American policy," Vance now says we want to work with the Marxist Angolan MPLA government "in more normal ways."

That elevates to policy U.N. Ambassador Andrew Young's arguments that we should trade a promise by Angola to stay away from Zaire's Shaba Province for our probable diplomatic recognition of the minority MPLA government. That government is kept in power by some 20,000 Cuban troobs, and if there are modern-day black echoes of a Munich-like sellout of Czechoslovakia this is it.

What is so astonishing about all this is its immorality. Forget for a moment the Cuban's role or non-role in Shaba. The highest intelligence sources tell me that now approximately 2,000 black Rhodesians have crossed from Angola where they were trained by Cubans to join Joshua Nkomo's army in Zambai which is trying to impose (not win through the vote) Nkomo as leader of the new Zimbabwe.

Then, forget that for a moment and consider the revolutionary situation in Angola. I know of no analyst of Angola who does not conclude that 90 percent of the black people of Angola are with the anti-MPLA, pro-Western movements, in particular Jonas Savimbi's UNITA in the South.

With almost no money or weapons, those poor, courageous people are still waging a brutal civil war against the highly equipped foreign Cubans Only a few weeks ago, Zbigniew Brzezinski, the other side of the president's conscience, was trying to find ways to aid UNITA. But that initiative was thwarted.

If it were only Angola, however, and only the 5 million black Angolans who don't want to live under the MPLA and the Cubans, I suppose one could argue for Vance's and Young' propositions.

In March, Young was quoted in the Zambian press as saying he would look favorably upon military aid to the front-line states: Zambia, Mozambique, Angola and Tanzania. Indeed, the core of the problem is that he has placed our policy under their whims, all in the name of "majority rule for Rhodesia, Namibia and South Africa."

Yet, two of these are Marxist and total failures economically, one is a totally subsidized "socialist" failure: the other is simply a sloppy economic failure. Not one has election or will have.

Yet all actively and militarily oppose the internal settlement in Rhodesia, which is going ahead with elections to turn the country over to black majority rule.

Why do black Rhodesian guerrilla leaders like Nkomo and the extremist Robert Mugabe, Andy Young's romantic favorite, not want elections? Even Africanists in the administration admit it is because neither one could win them.

Yet, in both places, we are supporting these revolutionary movements and not those who would bring real majority rule. In both places, we come out 1) in opposition to free elections, 2) in opposition to free enterprise and our own economic interests, 3) in support of further, all-out civil war in which hundreds of thousands of blacks will continue to be killed and 4) in favor of the final despotism and economic failure of the one-party states that surround them.

The argument on the other side, of course, is that the internal settlement will not stop the civil war. Yet, Nkomo waits. If the United States and Britain would support it, it is very likely he would come in. As it is, he has no need to.

So, incredible as it seems, this is what is genuinely behind the recent Vance statements. What is also behind them is the fact that people like Andy Young are surrounded by 1960s black-power activists who foresee in Africa what they were denied in the United States. They call it "revolution," but they really mean their own "power." They make Machiavellian Kissinger whom they so hate, look like St. Augustine.
