Calder Walton writes that a key issue remains although Mueller has issued his report: Is Trump an asset of the Kremlin?

Even taken on its own terms, the Nunes memo does nothing that Trump claims. But it does show us something—with deep ramifications for the intelligence community, the Russia investigation and maybe even the presidency

"...[T]he Trump-Russia scandal has the potential to spark an even more damaging US constitutional crisis than Watergate. Unlike Watergate, it involves a hostile foreign power and its intelligence services. At the same time that Mueller's opening indictments were unveiled yesterday, it was revealed that Russian-backed fake election content had reached a staggering 126 million Americans on Facebook during the 2016 election campaign. The Russia-Trump scandal, Watergate 2.0, is just beginning."

"Whether Trump likes to admit or not, we are now back in the territory of the Cold War. The White House would do well to study closely the history of that conflict— not least because the Russian government does so. As a former KGB officer, Putin lived the Cold War. His intelligence services today, the FSB and SVR, are known to look on the KGB’s history with pride."

"Both the Soviet Union and its western opponents, the United States and Britain, pursued covert action to interfere in elections during the Cold War. All of this, however, is not just about history: there are policy lessons for today from Britain and America's Cold War experiences."
