That's no whitewashing. Not sure where you got this idea from but if you read the link to https://en.m.wikipedia.org/wiki/Munich_Agreement you'd realize that what you wrote is completely incorrect and almost a lie. Czechia was not invited to that meeting and European superpowers decided that it should cede to Germany. Plus Germany invaded Czechia in 1939. Czechs would go to war and lost it in days (just look at the size and position) and would be a pariah in Europe if they didn't listen.
