The long-term biological effects will be felt forever. And the meteorological effects on the atmosphere will also. There will forever continue to be more than normal numbers of still-births, miscarriages, childhood cancer, and birth defects, as well as droughts and ultimate desertification in the parts of the planet that have been subjected to this kind of attack.
Possibly adding to the problem of radioactive contamination, is the proliferation of these pseudo-cloudbusters being deployed by followers of Don Croft and his role-playing game. I do not have any personal experience with the Croft devices, and cannot say how much effect, if any, they may have, but if they do anything, it would almost certainly be to make a drought worse.
How many of these things are there in the Balkans? How many people are there in that part of Europe who are using them? Would any of them listen if someone asked them to take down their equipment for a time to see if that would releive the drought? Or would such a request only make them hostile and suspicious towards the person suggesting that?
The PROPER and INTELLIGENT use of the cloudbuster could help the area recover, at least in a large part. But the present situation, where a large, but unknown number of ignorant individuals who really know nothing about orgone energy or cloudbusting except a few bits of misinformation they have learned from websites and discussion forums about "chemtrails" and other such non-issues, are likely to attempt to take matters into their own hands and build themselves a cloudbuster, will not help. It will only make things worse.
There are a few people in Europe who know enough about cloudbusting to be able to do something without too much risk of making the problem worse. But none of them happens to live in the Balkans.
And, as always, most people have jobs and families to support, and have to earn a living, so not many can just take time off from what they are doing to go someplace to do cloudbusting where it needs to be done. The only way that could be done would be if somebody was able to pay them enough to make up for not working at their regular job during the time they would have to spend on a cloudbusting expedition.
It is a bad situation, and is only going to get worse as the earth becomes more contaminated with radioactivity and more incompetents take up cloudbusting, or pseudo-cloudbusting, from irresponsible websites that promote it as a form of self-agrandizement.
