It's particularly unbecoming for the United States to act holier-than-thou about the use of Russian air power in Syria, when it is simultaneously trying to explain why American planes bombed a hospital in Afghanistan last month and killed 22 civilians. Neither Americans nor Russians gain anything by killing civilians; it's just an inevitable by-product of bombing.
But the biggest Western complaint is that the Russians are bombing the wrong people. Contrary to American and European assertions, they are indeed bombing the "right" people, the troops of Islamic State that Western air forces have been bombing for the past year. But the Russians are also bombing the troops of the Nusra Front and Ahrar al-Sham. They might even bomb the troops of the Free Syrian Army, if they could find any.
Don't they realise that these people are trying to overthrow the evil Syrian dictator, Bashar al-Assad, whereas the cruel and deluded fanatics who serve Islamic State are trying - well, actually, they are trying to overthrow the evil dictator Assad too. This brings us to the heart of the matter.
Western propaganda makes a systematic distinction between Islamic State (bad) and the "opposition" forces (all the other groups). The problem is that there is really little difference between them: they all want to overthrow the Syrian regime, and they are all Islamist jihadis except for the tattered remnants of the Free Syrian Army.
The Nusra Front was created in 2012 as the Syrian branch of Isis (now Islamic State), and broke away early last year in a dispute over tactics and turf. It is now the Syrian branch of al-Qaeda. Ahrar al-Sham was also founded by an al-Qaeda member, and is a close military and political ally of Nusra. And until the propaganda needs of the moment changed, even the United States admitted that the "moderate" elements of the Syrian opposition had collapsed.
There are no reliable statistics on this, but at least 90 per cent of the armed opposition are Islamists, and probably no more than 5 per cent are secular, pro-democratic groups.
There are not three alternatives in Syria. There are only two: either Bashar al-Assad's regime survives, or the Islamists take over.
Really serious Islamists, who hate democracy, behead people, and plan to overthrow all the other Arab governments before they set out to conquer the rest of the world.
They are probably being a bit over-optimistic there, but they would be seriously dangerous people if they commanded the resources of the Syrian state, and they would be a calamity for Syrians who are not Sunni Muslims. The Russians have accepted this reality, decided that it is in their own interests for Assad to survive, and are acting accordingly.
The United States and its allies, by contrast, are hamstrung by their previous insistence that Assad must go on human-rights grounds.
They cannot change their tune now without losing face, so they don't bomb Assad themselves, but they persist in the fantasy that some other force can be created in Syria that will defeat Assad and Islamic State.
Moreover, the leaders of America's two most important allies in the Muslim world, Turkey and Saudi Arabia, are determined that Assad should go and they would be very angry if the US helped him survive.
That, plus American anger at Russia over Ukraine and lingering hostility from the old Cold War, is why Nato is condemning the Russian intervention in Syria so vehemently. But it is all humbug and hypocrisy.
