Assange would not even have to lie outright, because the Russians would obviously never give him the emails directly. There would have to be one or more persons in between, because WikiLeaks is not in the business of taking leaks from governments. Assange might have strong suspicions about who originally hacked the DNC, but he did not necessarily go all out to confirm them.
Moreover, as Trump points out, the Central Intelligence Agency, the National Security Agency and the Federal Bureau of Investigation are the same organisations that cooked up the evidence for Saddam Hussein's "weapons of mass destruction" so President George W. Bush could invade Iraq.
Nevertheless, the US intelligence agencies are probably right to blame their Russian counterparts for the hacks that caused the Clinton campaign such problems. President Vladimir Putin has been quite open about preferring Trump to Clinton, and the leaks definitely gave a boost to Trump's election campaign in late July and August.
On the other hand, that happened so long before the actual vote in November that it's impossible to say if it had any effect on the outcome.
The event that probably did give Trump his very narrow margin of victory (100,000 votes spread between three key swing states) was FBI director James Comey's bizarre decision to declare that Hillary Clinton was facing another investigation only 11 days before the vote.
It's all might-have-beens, and the only reason it has become controversial is Trump's extremely thin skin. He is questioning the intelligence services' conclusions about Russian interference because he believes (wrongly) that they undermine the validity of his election victory. But his strong sympathy for the Russian position, though driven by perceived personal interests, is a refreshing break from the usual Washington paranoia.
He said it himself (in another tweet): "Having a good relationship with Russia is a good thing, not a bad thing. Only stupid people or fools would think that it is bad. We have enough problems around the world without yet another one."
This is a perfectly reasonable statement. Trump's views on China give cause for alarm, but his desire for a reconciliation with Russia makes more sense than the reflex hostility that both Hillary Clinton and the US intelligence services bring to the relationship. Vladimir Putin is a player, and sometimes he plays rough, but his recent meddling in the American election is far less than the massive US interference in Russian elections in the 1990s.
In seeking a rapprochement with Moscow, Trump should not make the mistake of accepting Russia's illegal annexation of Crimea. Changing borders by force (even if most of the local population approves of it) has been banned by international law for more than half a century, and we should not start making exceptions to that rule now.
But while the United States never accepted the old Soviet Union's illegal annexation of the Baltic states in 1940, it did not let that stand in the way of improving the US-Soviet relationship as the Cold War drew to an end.
There is much that the United States and Russia could usefully cooperate on now, starting with putting an end to the war in Syria. On this issue, at least, Trump is right and Obama, Clinton and the spooks are wrong.
