Do you have examples of appeasement that did work? Please share them....
They happen every year, but you don't hear about them because they are not as attention grabbing as that instance in 1938.
For example, my own country successfully demarcated a border with China, with whom we fought an undeclared war over the same territories in the 1960s. Russia was a loser in this exchange of territories, but instead it settled its disputes with China once and for all, and was able to begin building a working relationship with the most populous country in the world. India and China, meanwhile, are still not able to fully demarcate their border, and this represents a constant risk of a full out war, as well as acting as a break on both countries' economic potential.
Other countries that neighbor China, have handed over huge chunks of territory willingly. The local nationalists were of course livid, but again - those countries were able to establish working trade relations that enormously benefited their economies, and simultaneously removed the risk of conflict with China. Is this the foolish appeasement of a dangerous imperial power?
Is it better to be like the Philippines, being prodded by America to fight tooth and nail over every island reef, all the while risking a confrontation with China? Would it perhaps be better for the Philippines to accept the loss of some islands, but instead guarantee themselves a beneficial and peaceful relationship with a huge neighbor? I don't know.
Point is, appeasement happens every year, all around the globe. Smaller, weaker countries routinely have their arms twisted by bigger, stronger countries. Whether it's over land, or water rights, or forced military access, or what have you. If every single one of those East Timors and Kurdistans got into a pose, and declared a fight to the death for their freedoms and values against their predatory neighbors - it would be a pretty miserable result.
1938 is simply a bludgeon with which hawks have been beating everyone since WW2.
Last example, let's look at Hong Kong.
1) China was promised it would be returned.
2) Many people felt it was wrong to "abandon" the Hong Kongers, and that it represented a betrayal to hand it over to Communist China.
3) When it was handed over, it immediately came to represent 25% of Chinese GDP.
4) Are Hong Kongers less free now? Yes.
5) Are many Hong Kongers unhappy with the new arrangement, and as a result moving to places like the UK and Canada? Yes.
6) Was it still absolutely right for the UK to keep its word, even before an odious regime, and over the heads of a free and prosperous population that wanted to remain with the UK? Of course. Britain benefited enormously from friendly relations with China, and the world was freed of one more potential hotspot.
If promises to Russia were kept, this would similarly be seen as appeasement and "bending over" for Russia by Poland and other Eastern European states. However, it also could have prevented the current conflagration. Just to be clear, I mean not the EU but NATO.
