Money was the reason why many former eastern block countries joined EU. Where is the money for revival of Ukraine? They are huge country with 45 million souls. They need hundreds of millions of euros, just to get on their feet. Who has that kind of money? Germany probably think Greece and others will pay the debt so they can help Ukraine. Good luck with that.
By available data on internet, average salary in Ukraine is around 3300 of their money which translates to ~120 euros. With 120 euros in any "developed" and "developing" EU country you can wipe your ass off and nothing else.
if you (lets say germany) invest money somewhere (lets say ukraine) its not like those money are completely wasted. german companies/industry/banks/..... will settle in ukraine and will eventually generate profit there. this is how it works, i can see it on my country where major banks are foreign ones, the biggest industrial company is german etc. is it a good way or a bad way? well its neither, its just how it is. but if our companies would be run by our businessmen we'd (as people) be doing far worse. so i kinda accept it as it is. btw association treaty is only 1st step, it would take couple of years until ukraine would be fully accepted into eu.
if you don't know if the greek dept will be paid i can tell you for sure that it will be paid. do you know why? because all depts are always paid in full and there always has to be somebody who pays for it, being the one who borrowed, lended money or somebody completely "innocent" that just happened to have money when he was around. and i can even tell you who will pay the dept.
- for sure its not going to be paid by that southern nation with their sickening work ethics that makes them drink frappe 8 hours/day while they spend the other 8 other hours dreaming about communism and blaming merkel for their misery.
- for sure its also not going to be paid by german or french banks, because their claims were in big majority already paid in previous years
- and now try to guess who will pay it....
its going to be paid by me, by you, by your mum and by my grandfather if he hadn't died 20 years ago and every other european that at least once in his life paid taxes. thats what is european finantial stability facility fund for.
