Main question is what Poland want. Is that Intermarium as Pilsudski suggested (balance between western Europe and Russia) it or Poland by the Kanopisht (Clero-Catholic Poland, Vatican-Germanic project, as ultimately anti-Russian creation).
...as far as Międzymorze is concerned, but apparently there is one sea missing in Intermarium - Adriatic.
If its Intermarium Poland want, then you don`t worry for Adriatic. You know how Adriatic came to Slavic hands? First, it was always populated by Serbs, even when Rome, Venice, Hungary or Austria controlled it. Then Serbs liberated it and opposition countered with project of `Clero-Catholic Croat nation`, firstly, out from Catholic Serbs and then also from converted Orthodox Serbs. Then finally, Serbian state liberated Slavic/Serbian part of Adriatic and won it for the Slavic world. But Serbs mistaken. We didn`t listen good Polish Czartorisky and we didn`t create Greater Serbia (as he pointed out- Greater Serbia is just ethnic natural Serbia, ie where live all Serbs, of Orthodox, Catholic and Muslim faith), after WWI but, we fell in trap of creating Yugoslavia. We now know that Yugoslavia was Vatican`t and cominetrna`s trap for Serbs, with consent of western Europe and USA, our allies who betrayed us.
All in all, its not over yet. Things change rapidly. How things stand, all states, except Serbia, created from the ruin of former Yugoslavia, are semi-states, puppets, false states and not able to exist in real world, out of their political projects. For various reasons. Apart from Serbia, only Slovenia may be exception here.
In any case - the core is already there - V4. If we add Romania to V4
Conditionally. As I said, all depend on what Poland or to say it correctly, what those who lead Poland want or to say even more correctly, depending on what world powers already agreed to be destine of Poland. In any case, Poland, Poles and those who love them may try to at least tackle and affect things.
I will tell you what political commentators in Serbia says and they knows. Sums up of it is that when collapse, EU is going to split on at least two conglomerates. 1. Western Europe (French-German axis), 2. Poland (by Kanopisht), 3. Serbia (extended so called working title `Little Shengen` or it would be 4. Poland-Serbia (Intermarium or New Commonwealth).
In game is also `Orthodox Union` but, essentially, its rather trap same is `Kanopisht` is trap for Poland. So, more and more in Serbia we speak of `Little Shengen` and `Little Shengen plus` as working title. Hungarian Orban is wise and he speaks of `Visegrad plus` and call Serbia to be main plus in it, while at the same time don`t see survival of Croatia. Orban speaks real politic and possible speaks in name of those in Poland, as possible agreed, ... those who knows that Poland have no true option but Intermarium.
Serbia, on the other side, when once consolidate entirely, when dust in the region settle down and Serbia encompass of at least 60-70% of former Yugoslavia, all would want with Serbia, even Visegrad members. Its about ideology and spirit that Serbia promote and defend. Its about only force that can make things normal again, that can make us all great again as we truly are great and that is `Sarmatism`, that essentially refuse any foreign rule over us and care for all our specific interests.
But Poland have it in itself and we wait for Poland. Corey Lewandowski knows it. We Serbs wait for Poland to awake.
Corey Lewandowski in Belgrade, some year ago, in talk with richest Serbia`s economic magnates, with Serbia`s decision-makers; few days after this lunch Cory Lewandoski opened private Polonia`s company that established money flow with Serb Bosnian leadershipI've got a feeling that Austria is a
Austria becoming interesting in combination if Pan-Serbian card is activated, if entire Germanic world start to fall apart and return to its natural/original Slaveno-Serbian state, if the parts of very Germany secede from Germany and seek joining to rising Intermarium or some Central-European Union led by Belgrade, while rest of Germany join with France in some future Western European Union or Western European Union plus (read plus Northern Africa).
Sure, this scenario or any other depend on agreement between three main world powers, USA, China and Russia. I heard, I had right information. New Yalta is truly suggested to happen in June in Belgrade.
