Oh, so you're saying that "Czechoslovaks", in fact, wanted to defend their country?
Military wanted, politicians not so much.
Without a doubt. I can imagine a coalition of the Baltic States, Finland, Poland, Romania, Czechoslovakia and Yugoslavia easily
The only militarily viable coalition would be Poland, Romania and Czechoslovakia, optionally Hungary, the problem is nobody in said coalition liked each other enough to do business with.
Yugoslavia was militarily worthless, it had numerically a huge military but the actuall usefull force was less than 100.000 soldiers.
