I think that the EU's accession process is a good and just order that is based on principles and beliefs of what is need to make a good nation. Some of these principles include a nation being able to adhere to the spirit of a democracy for all citizen to live by.
No, they need to let it go and settle its own self, which is what will end up happening. If the leaders just let this go, soon it will all end. If they keep jumping in on it and trying to rush things, then they will mess it all up and just cause more trouble for the people.
The European Union uses a combined financial influence in which countries that want to participate have to tow the line so to speak. Any country for example will experience terrorism, which is not necessary under control of the government, so to hold a country at bay for problems not necessarily under their control would be unfair. It seems like financial manipulation in an attempt to umbrella a country under the European Union's policies.
I don't believe leaders should unfreeze the EU accession process. This is because a freeze was put in place for a reason to begin with. The accession process has its own group of problems and those need to be dealt with before any speak of unfreezing can come about. The EU will eventually deal with the problem.
EU access only allows those that have proven themselves to fit certain criteria. If these criteria are not met, then access cannot be approved. Sacrificing principles does not equate to morality or logic. The accession process is frozen due to financial difficulties within the EU. Once the countries are more stable, the process may re-open to applicants.
