How likely is it for Czechoslovakia to annex the Glatz/Kladsko/Klodzko region of Middle Silesia after the Treaty of Versailles (1919), and what would have happened after that? What are the effects on the Czechoslovak Economy, the Sudetenland Question, and the situation in Silesia overall (especially concerning Poland's aims towards Lower Silesia)?
If WW2 still happens ITTL and Germany still loses, then how does this affect the land settlement in Silesia and Pomerania?
