Indeed. On other side, Hungarians know they will very likely not keep everything they gained from Czechoslovakia. Especially if Slovakia will get back under Prague influence. They gained some 1500 sq km, 74 villages. Basically not a single one of them Hungarian. Well probably you would find few. What they gained by March 1939 military action against Ruthenia and Slovakia will be biggest question, however even some Vienna award gains are very questionable.He can try. He's trapped between two options - the longer he waits, the more leverage he has over the Hungarians and the less over the Czechoslovak government in exile and the Entente in general. Problem is, he really needs to keep both happy and this isn't possible.
Tiso on other side have option to mobilize and jump in towards Protectorate. His northern wing is protected by mountains as well as insurgent Poles and attacking Hungarians. Heck if he does nothing, he got standing army and nation who got smell of independence while Czechs got 1 division in France which is 50% percent manned by Slovaks. Will be allies willing to proceed against Slovakia? Maybe yes and indeed it is bit to big gamble. But after all Slovak Independence was proclaimed by democratically elected Slovak Diet.
From my reading over 100K Poles were in Hungary during WWII. From these some 30K made it to West OTL.Interned Poles will long since have "escaped" in dribs and drabs and will be either in France or fighting in Poland with the ZWZ.
About right from Sopron. I guess most western area towards Wien. 54 km from Bratislava. But Slovaks are protected by Danube here so I wouldn't bother in their place to much. In my opinion their political points are in Protectorate.75km or so...
Hungarians had app 12 pieces of different versions of TK. Used for training or as a tractors. Not really reason to bother to transfer them to Poland from military POV. If they can find few guys among polish refugees who served on them and used it for PR reasons that could be bit useful. But with strained logistic questionable.Tough to get them anywhere useful though...
