Just listened to "Ghosts of the Ostfront" from Dan Carlin's Hardcore History podcast.

You really, really don't want to invade Russia.

It's hard to defeat people who don't even value their own lives and won't surrender even when their cause is hopeless. Most countries would have sued for peace in 1941, but Russia kept fighting, and just threw millions of their own people into the meat grinder.

I would argue that the blunder at Gettysburg was committed by Robert E. Lee rather than Pickett. The plan was Lee's, and he's the one who insisted on going forward with it even over General Longstreet's objection. Pickett is just the one to whom it fell to try and make the bad plan work.

The question on annexation by Germany in 1938 needs to be changed to include Austria. Parts of Austria were also annexed by Germany in March of 1938 and since this was the only annexation I was aware of I didn't have any other alternatives. Please amend.

The only thing about the question that could maybe be improved is that Britain did a lot worse than just allowing annexation. They actively negotiated away the Sudetenland from Czechoslovakia to give to the Reich.

The Germans did just fine invading Russia in World War I. Granted their greatest victories took place in August and September of 1914, but they still managed to rout the numerically superior Russian forces in the early stages of the war and to defeat them in almost every battle that followed. Competent leadership and better logistical systems overcame any problems that the sheer size of the front or the Russians' supposed indifference to their own lives might have posed.

Nor is weather a sufficient explanation, although it made Napoleon's and Hitler's mistakes all the more disastrous. There's a line in "Grand Illusion," Jean Renoir's classic film about French prisoners of war during World War I, in which one of them ruefully says to the others in the prison yard: "And General Winter, who'd kill off the wicked Boche, but act as a tonic for the Allies." Just as generals are always fighting the last war, we tend to overgeneralize the lessons of the past.

I have read things written during the time of the Ottoman Empire which refer to it as Turkey. They give me the impression that although the official name was the Ottoman Empire, people didn't call it that in ordinary speech, just as people today don't often talk about the Hellenic Republic. Or at least that Turkey was at that time a generally understood unofficial name for the country.

Just for the record, the US was entangled in Vietnam long before 1965.
+6
Level 73
Aug 12, 2020
True. During WWII the US supplied Ho Chi Minh with arms and guerilla training to help his Viet Minh fight the Japanese, which came back to haunt them when he became an enemy. As communists came closer to taking over, no US president wanted to go down in history as the one who allowed Vietnam to fall to communism and they kept increasing troops and support. Historians say that President Kennedy planned to have all troops out by 1965. After Kennedy's assassination, Johnson took over and felt he had to send in more troops to appease General Westmoreland. Nixon used the war for political gain and prolonged it, but at least he finally ended it. I heard his speech on TV and cried because my husband had a low draft number and would surely have been called up had the war not ended.

They wouldn't have gotten involved (on the side against Ho) in the first place except that deGaulle demanded it, and as France was crucial to Western Europe's resistance against Communism and the Soviets, the US gave up their support for Vietnamese independence. Roosevelt said the year before this, "Indo-China should not go back to France...France has had the country...one hundred years, and the people are worse off than they were at the beginning."

Challenger's O-rings weren't faulty. They were the same as the O-rings in every successful shuttle mission, but they were operated outside of their design parameters. NASA was aware that it was too cold to launch. The disaster wasn't caused by a mechanical failure but by human error. A more accurate clue – which would actually make it a blunder – would be, "This space shuttle explodes after launching under unsafe conditions."

Churchill gets off very lightly for his disastrous strategy against the Ottoman Empire including the failed Gallipoli invasion. A few days before Britain declared war on the Ottomans, Churchill (as First Lord of the Admiralty) ordered a naval bombardment of the forts at the Narrows in the Dardanelles which achieved nothing other than to alert the Turks who quickly began improving their coastal defences - just in time for Churchill's second plan for the ANZACs to invade at Gallopoli, which also achieved no strategic gains and was abandoned after much loss of life on both sides.

? Russia has successfully annexed the largest amount of territory since something like WWII. And arguably at an extremely low cost of life for them. They're successfully fighting against something like 40-50 of the most-developed countries on Earth. They acted; Europe was shown to be meek.

Anyone can argue the financial cost, and set whatever boundaries on that as they wish. Or "reputation" (as though any of the permanent UN SC members care).

In 50 years who will be controlling the territory? Looks like Russia; same country that controls it today.

Morton Thiokol is an American company--where did you get UK? And it was Morthon Thiokol managers who overrode their engineers and called their data "inconclusive", contributing to the blunderous decision to launch. No company or organization is an unheard hero here.
