And the useful idiots who now believe that the army is on their side, the secular democrats of the left and the opportunistic Noor Party on the religious right, will in due course find themselves back in the same old police stations, being tortured by the same old goons.
So should outsiders just stand by and watch it all happen?
What are the alternatives? Well, President Barack Obama told the generals off in no uncertain terms after the biggest massacre on August 14. "We appreciate the complexity of the situation," he said sternly. "We recognise that change takes time," he added, his anger mounting steadily. "There are going to be false starts and difficult days," he said, almost shaking with rage.
"We know that democratic transitions are measured not in months, or even years, but sometimes in generations," he concluded. "But our traditional co-operation cannot continue as usual when civilians are being killed in the streets and rights are being rolled back."
And with that, he cancelled the Bright Star joint US-Egyptian military exercise that was scheduled for September. Obama added: "I've asked my national security team to assess the implications of the actions taken by the (Egyptian) interim government and further steps we may take as necessary with respect to the US-Egyptian relationship."
Egyptian generals did not stop killing people upon hearing all this.
The inaction of the United States is due to two causes.
First, the only major leverage at Barack Obama's disposal, cancelling the annual $1.3 billion in aid that Washington gives to the Egyptian army, is no threat at all. It would instantly be replaced, and probably increased, by the rich and conservative Arab monarchies of the Gulf which approve of the coup.
Secondly, Washington remains transfixed by the notion that its alliance with Egypt is important for American security. This hoary myth dates back to the long-gone days when the US depended heavily on importing oil from the Gulf, and almost all of it had to pass through Egypt's Suez Canal. Today less than 10 per cent of the oil burned in America comes from the Middle East.
There will be no major military intervention in Syria either, although outside countries - both within the Arab world and beyond it - will continue to drip-feed supplies to their preferred side.
So what's left of the Arab spring? On the face of it, not much. Tunisia, where the first democratic revolution started three years ago, still totters forward, and there is more democracy in Morocco than there used to be, but that's about it.
The non-violent democratic revolutions that have worked so well in many other parts of the world are not doing very well in the Arab world.
There may be many reasons for this, but one stands out above all the others. In the Arab world, unlike most other places, two rival solutions to the existing autocracy, poverty and oppression compete for popular support: democracy and Islamism. The result, in one country after another, is that the autocrats exploit that division to retain or regain power.
