Does Croatia want to annex Republika Srpska? As far as I know, present-day Srpska used to be part of Nazi Croatia during WW 2.
Croatia can't annex Srpska because foreign powers wouldn't allow it, but their leadership would love to help Bosnian muslims destroy it, and make a muslim dominated Bosnia.
I don't know if we would be able to defend ourselves, because NATO, USA and Europe weakened our army, and who knows if Serbia would intervene. On the other hand, I don't think Croats have the will to die for something like that.
Croatia wouln't have the courage or foreign support to do it. Why? Primarily because of today's Putin Russia (not 1990's Yeltsin's) is fully supportive of Republika Srpska and have massive investments in Srpska. I strongly doubt that they would try. Further, Croatia's economy and Muslim/Croat Federation is severely bad due to great decrease of foreign aid. For the past few years, RS economy has been much better than that of the other Muslim/Croat Federation.
Croats would definitely not want Muslims to have full control of Srpska because if it happened, Croatia would definitely be next of the list of islamization. It would also signal the fall of Tadic's traitorous regime by the people, just like the one in 2000. Nationalists would be back in power (which I would welcome), volunteers from Serbia & Montenegro, arms from Russia & China. Yes, both Russia and China have economic ties in RS. You must look at it more at an economical, rather than military aspect. Everyone protects their own economic interests.
Since Milorad Dodik (my favorite Serbian leader right now) came to power, Western powers together have been trying to overthrow Dodik, but are yet to do so because of Dodik's popularity and again, Russia and China.
Istra Peninsula has a large Italian population and was NEVER part of Croatia. This Italian population and even good part of Dalmatian coast is pro-italian, rather than pro-Nazi Croatian. Since 1945, they have wanted to be part of Italy. Many Serbs mistake those who live in Dalmatia to be pro-Nazi Croats, but that is so innacurate.
NATO would not be able to get involved because according to it's own rules, which they themselves have broken often, NATO allies help each other "ONLY" when one of the members is attacked, not if they are attacking someone.
In conclusion, Croats have enough of their own problems.
Would I personally like the war to occur. That is a hard question to answer because I am against killing innocent civilians, even Croatian civilians due to some egoistical idiot who wants it. Why he said it? Maybe because he is smoking some good chronic.
On the pro-war side, I would like to see some old scores settled once and for all. I don't think that Serbs should take the whole country, but rather take only what is rightfully ours, Italians take what's rightfully theirs....no more or less. This would pretty much make true croatia the size of Rhode Island (no offense intended to Rhode Islanders). Pretty much, Zagorje (area around Zagreb) would be central Croatia. Those are the Croats that you have to be careful with because those are the true Croats and would kill anyone who isn't a Roman Catholic Croat, period.
You have to understand that eventhough what they did to us in the last 100 years, that nothing goes unpunished. I just hope that if it happens, that Serbs will show more mercy towards Croats than they did towards us. We have to learn how to play the game on our own. Western economies and influences worldwide are slowly dissipating ( NO $$$ for new wars),while new economic blocks are taking over. If anything, this insult by Croatia is nothing but a last attempt to stop this, but to no avail yet. Current Croatian foreign debt is over $45 billion, some of it to Russia and China.
For example, in 2008, during the Georgian war, Western Powers, led by US were testing Russian response. I believe that they were completely shocked by the intensity of the Russian force that the conflict taught them that today's Russia will not allow someone to get involved in their zone of influence. NEVER COMPARE 90'S RUSSIA TO PUTIN'S RUSSIA because it is an understatement. Putin has more than once shown this...remember Chechnya...what's Chechnya..........exactly).
