Some Brits have a serious problem accepting that the US played a huge part in our success in WW2.
There is a strong argument that neither Britain or the US would have got anywhere if it wasn't for our allies at the time, the now-defunct Soviet Union.
Over the course of the entire war, Britain and the US lost about 400,000 lives each (and that figure includes a relatively small amount of civilian deaths) while the Soviets lost over 20 million lives. More than half of those were civilian deaths caused by slaughter, famine and so on, but they still lost about 10 million soldiers. Yes, that's 10 million.
Like our own losses that we've been remembering this week, each one was a tragedy for those left behind, but the statistics for Soviet losses are staggering and dwarf anything that happened to what we now call the western allies. For instance, on D-Day itself, the UK, US and Canada suffered a total of 2,500 deaths. In the Battle for Berlin in the latter half of April 1945, almost 100,000 Soviet soldiers were killed.
Yes, the US played a fairly important part in the outcome of the war, but the Soviet Union's role was absolutely critical.
