Is it important to get historical facts right?
David Cameron has been criticised after mistakenly saying the UK was the "junior partner" in the allied World War II fight against Germany in 1940. Should he face criticism for saying this?
"We were the junior partner in 1940 when we were fighting the Nazis" he said during his first trip to the US as prime minister.
However, the US officially declared war on Germany on 11 December 1941, shortly after Hitler launched hostilities against the US and four days after the Pearl Harbor attacks which drew the US into conflict with Japan.
No 10 said Mr Cameron had not meant to belittle the efforts of British troops.
What do you think of David Cameron's historical slip? Could his mistake alienate former troops? Is it important to remember historical dates? If so why? Given his speech was about the relationship between the US and the UK and not about WWII, does it matter that he got the facts wrong?
