But there is also thje fact that Great Britain and France openly allied with the Soviet Union prior to Operation Barbarossa in 1941. The fact that both nations were imperial powers didn't stop this diplomatic development in OTL. Also consider that when the Japanese attacked the U.S. in December 07, 1941, as shown by the 1942 and 1944 elections, the progressive Democrats and Republicans were able to drive out the isolationist wings of theeir parties....But can you imagine a Republican congress shipping aid to the Soviets, even if a US-German war started? Soviet remnants declared war on Japan after Pearl in just such a ploy, even going so far as to send a division into Manchuria, but they didn't get one pair of boots. Any isolationist Dem-Rep majority would leave the two to kill each other, not insure that one or the other won entirely. The President may lean in one direction, but Congress is the one who has to buy the boots and tanks to send.
It was only after the 1945/1946 invasion of Japan during Operation Downfall, and the 1951 U.S. intervention in the Chinese Civil War, was ground placed for the 1952 "Fortress America" speech by Robert Taft (R-OH) during the Republican National Convention did the idea of isolationism become popular again....
There's always the German complaint that much of those events were done with clandestine US/Canadian support. After the monarchy fled with much of Britain's own top secret research (such as early jet engines) and scientists, they carved out substantial British communities in North America. Even the ELA has unofficial speakers who tour the nation, asking for donations. And since Germany can't exactly force the US to do anything about them except by making huge concessions of their own...
That's also what the German government said after the 1985 Kaiserplatz Massacre, when they fired on the thousands of pro-democracy student protesters. It didn't help matters when President Jack Kemp (R-NY) referred to the leaders Michael Kühnen and Meinolf Schönborn as the "Butchers of Berlin" in the speeches during the 1986 and 1988 elections.
The claims of a "covert war" seemed to also take place after the 1998accidental SEATO/ANZUS bombing of the German embassy in Jakarta during the Indonesian Civil War. Yet they still have been asking since 2001 for the U.S. to allow the Third Reich into the World Trade Organization (W.T.O.) despite a horrible human rights record.
As for the "ELA connection", one White House meeting in 2002 between V.P. Paul Wellstone (D-MN) and Jude Law and David Beckham seems to be a rare exception. Despite the claims of talk-show hosts Newt Gingrich and Rush Limbaugh. Despite what anyone says, there have never been any OSS agents in Europe since the executive order was signed in 1977....
