Perhaps negotiating a settlement would have worked? Although Poland would then have had to live up to the commitments it made in the settlement agreements and experience shows that Poland was pretty terrible at doing that between 1918 and 1939.
see how litlle or nothing You know? Piłsudski send a note to Masaryk asking for negotiations, the response on Czech side was- occupation of Spis and Orawa, than attack on Śląsk Cieszyński, which was a breach of 5 November agreement
2 February agreement - again breach on Czechoslovakian side( for example attack between 21-24 February)
also add to this killing of Polish POW
Do you have any links to anything which in any way supports any of that? Or did you just pluck it from the air?
this is pretty common knowledge, why would Poland agree on not taking the plabiscite if it wasnt for this???,doesnt make any sense. Read a book on the topic, if You speak Polish I can give You few titles
