But it is already possible to see certain diplomatic realignments -- some aspects of foreign relations may never be the same again.
One of the early surprises was the revelation of the extent to which Arab fears of a future nuclear-armed Iran have put them on the same page as their traditional foe Israel in pushing for military action against Tehran.
Washington's inability to keep its secrets secret has seen it lose face with rising rival China, and Beijing has been careful not to let its own guard down, giving a careful response to leaked criticisms of its policy.
European governments have denounced the documents leak as irresponsible and dangerous, and some leaders have been embarrassed by the often frank opinions US diplomats have of them, but most denied the slow dump has harmed ties.
But some have been upset, such as Poland, which since the end of the Cold War has invested much in what it thought were warm ties with its US saviour, only to find out through WikiLeaks the affection was not entirely mutual.
"We have a really serious problem," Polish Prime Minister Donald Tusk told reporters, after learning that the US has no plans for a permanent military garrison in Poland.
"It's the problem of losing illusions over the character of relations between different states, including allies as close as the United States and Poland," he said.
A senior European diplomatic source said he thought Poland would now concentrate more closely on its ties within Europe, and spend less time courting Washington.
Russian President Dmitry Medvedev said the leaks "show the entire extent of the cynicism of these evaluations, these judgements, that prevail" in United States policy.
The cables paint Medvedev as playing Robin to Prime Minister Vladimir Putin's Batman, while Putin himself is described as an "alpha dog" and a "behind the scenes puppeteer" dissatisfied with his role.
So far, the US memos that have been published dress far from flattering pictures of several other leaders. But again, it will be some time before the repercussions for relations between heads of state emerge, if ever.
German Chancellor Angela Merkel is deemed "risk averse and rarely creative", French President Nicolas Sarkozy is "thin-skinned and authoritarian", Italian Prime Minister Silvio Berlusconi is "feckless, vain," and British Prime Minister David Cameron is "lacking depth."
Turkish Prime Minister Recep Tayyip Erdogan is guided by an "iron ring of sycophantic (but contemptuous) advisors," US diplomats wrote, while his Foreign Minister Ahmet Davutoglu is "exceptionally dangerous."
Libyan leader Moamer Kadhafi praised WikiLeaks for exposing US "hypocrisy", saying the cables prove that "America is not what it has led allies and friends to believe it to be."
Kadhafi said the website's role was "very important in revealing the plots which are hatched behind the curtains against persons and peoples," but warned it could lose credibility if it started "to damage people's image."
Former South African president Thabo Mbeki, currently mediating an election crisis in the Ivory Coast on behalf of the African Union, does not escape the US diplomatic pen, being portrayed as "irrational" and "hypersensitive".
And in the Middle East, where the leaked memos led to "misunderstandings", they gave Arab leaders' private words a rare public airing.
Saudi and Bahraini leaders called for a US military strike on Iran over its controversial nuclear programme, with Saudi Arabia's King Abdullah asking Washington to "cut off the serpent's head."
Israel congratulated itself on what it said was the vindication of its own calls for action against Iran. Tehran told its Arab neighbours not to fall into the "trap" set by WikiLeaks, a "project of Iranophobia and disunity."
