It sure seems to me that too many people looked the other way, and still are, about Russian attempts to influence the 2016 US election. Even the bipartisan intelligence agencies confirmed the Russian activities. Considering the Russians favored the Republicans it was, and still is, the responsibility of Republicans to address the matter. The 'party before country' factor is considerable. The continued denial will affect everyone eventually. I think it is wishful thinking to assume the Russians will continue to support the Republican party. That would eventually give the Russians some control over it. The Russians just support Russia and since World War II, at least, have done everything possible to counter Western interests. And I think they will continue to do so for the foreseeable future.
I suspect the European Union is quite concerned about the direction of United States politics and goverance.
