No, Germany was going to lose the war no matter what by the time America came to the UK and Africa when they had some influence in the battles against the Nazis around late 1942. It wasn’t too soon after that in very late 1942/jan of 1943 time Russia was massively pushing on the eastern front and winning huge victories when in the years prior they had almost been entirely defeated, the Germans took the front all the way up to Moscow even now they were taking the front up to Berlin. For Britain and the rest of the Commonwealth with Free France they were on they were part way on their 7th campaign when counted collectively with the rest of Africa and the middle east when they had won the 6 others prior. Which led ultimately to the fall of the Italian empire. Which the US joined for the very last part of these campaigns. The western front (if you could call it that) prior to 1944 was a stalemate. The Axis couldnt invade Britain sucessfully due to the fact the Commonwealth had superiority of the skies since the start of the war with the Battle of Britain stating just that, let alone the Navy. But at the same time the Commonwealth couldn’t land on the West of the European mainland either because of the Nazi’s had set up vast fortifications in preparation.
Had the US not joined the Commonwealth may not have made a successful invasion until later on in the war when the Nazi’s would have most likely realised they needed to attempt to protect the Eastern front and Berlin more than having power over a few Western European nations. And therefore would have had to a lot of pull troops and resources back to Germany making it possible for the Commonwealth to make a successful invasion of Nazi territory and liberation of Western Europe. And subsequently we would probably have ended up with a similar situation today where ex-soviet countries having Russian taught in schools as a second language. Provided the USSR still dissolved in 1991. Amidst the rooting tension of the Coronavirus outbreak that has engulfed over 720 lives and has infected more than 34,000 people, many nations including India, Bangladesh, Uzbekistan, USA, Taiwan, Brazil, Italy, South Arabia, South Korea took initiatives to evacuate their citizens from China. However, Pakistan, perfectly playing the role of an iron brother, declared that they won’t be evacuating the 800 Pakistani students trapped in China (majority being from Wuhan); and the only reason to deny the rescue operation is to stand in solidarity with China during this crisis period. Dear Pakistan, how ever hard you try to use the veil of the so-called ‘solidarity’ and cite other ‘larger interests’ of the region and the world, you cannot hide real reasons the decision reflects.
