One thing is clear from NATO's latest bombing blunder in Kosovo. Its officers do not read The Irish Times.
Had they done so - or read half a dozen other newspapers and magazines, including Time and Le Monde - on Friday morning, they would have seen that the building they later bombed on Mount Kosare, just inside the province, killing one man and wounding 15 more, was in fact the forward headquarters of the Kosovo Liberation Army.
"The target which was struck by NATO was done so on the assumption that it was still in the hands of the Yugoslav army," said the NATO spokesman, Mr Jamie Shea.
The blunder is, in its own way, as mystifying as the attack on the Chinese embassy in Belgrade, which would have been avoided by studying a tourist map of the city, because at least one part of NATO knew the Kosare base was a rebel headquarters.
For more than a month beforehand, regular reports on who controlled which bits of this mountain were fed to NATO on a satellite fax link from the rebels based at Kosare.
It also appears that international officers with a nearby observation point of the Organisation for Security and Co-operation in Europe (OSCE) sent the same reports.
NATO acted on these reports, bombing Serb units just outside the rebel enclave to help the KLA push its units further into Kosovo.
NATO yesterday refused to comment on how one part of the organisation could have had this knowledge and not passed it to another part, something they said would be "tightened up" following the Chinese embassy bombing.
"Prevaricate? What are you saying?" said a spokeswoman, Ms Christina Gallach, at NATO headquarters in Brussels.
"The change of presence in the military compound was not known to us. The fax may have arrived, but I am not aware of it."
Visiting Kosare two days before, I was told by KLA officers that they frequently sent NATO targeting information on Serb units opposing them.
Kosare, a red-brick building, lies at the bottom of a steep gorge one kilometre inside Kosovo and is well inside a pocket established by the KLA soon after NATO began its air strikes.
The pocket, anchored on the Albanian border, extends for a further three to four kilometres beyond Kosare, which is the only building in an area of dense woods and steep ravines.
Sitting out a burst of Serb shelling around this building, I was told by rebel officers that there was nothing to fear because the post's position was hard for the Serb gunners to hit. They were right.
Units there showed off the casings from one of several NATO cluster bombs which have been falling on Serb units on the outer fringe of the enclave. One week ago, a group of American forward observers arrived in the area, setting up a base in the hills. Last night the KLA leader, Mr Hasim Thaci, said he accepted that the bombing was a "technical mistake."
The KLA is at present trying to convince NATO of its democratic credentials, hoping this will lead to the Western alliance giving it better air support. Senior officials said the mistake had been made and nothing would be gained by criticising NATO, with Mr Thaci saying: "Air strikes must continue."
But the KLA will be hoping that in future NATO at least reads the faxes it sends, or reads the newspapers.
