Uhhh....ever read up on The Six Day War? Israel has been stirring up shit with its neighbors for DECADES because it knows the USA will always be there to cover its ass if the excrement hits the cooling device.
Allow me to quote the former defense minister Moshe Dayan "After all, I know how at least 80 percent of the clashes there started. In my opinion, more than 80 percent, but let's talk about 80 percent. It went this way: We would send a tractor to plow some area where it wasn't possible to do anything, in the demilitarized area, and knew in advance that the Syrians would start to shoot. If they didn't shoot, we would tell the tractor to advance farther, until in the end the Syrians would get annoyed and shoot. And then we would use artillery and later the air force also, and that's how it was. I did that, and Laskov and Chara did that, and Yitzhak did that, but it seemed to me that the person who most enjoyed these games was Dado."
well, call me a conspiracy theorist or not but that's what i believe happened on 9/11, just like the Lavon Affair... They want Iran and will do anything to get it. I think American's are sick and tired of Israel deciding its middle eastern affairs, people need to realize that they're being played. I'm seriously afraid of Ahmadinejad going any further with Nuclear Energy research because the further he gets, the easier it is for somebody to frame them. My suggestion would be to dump nuclear ambitions and use most of their desert to harness the Sun's energy, not sure how it fairs during dust storms or if there are much there but give Israel something new to look for -- next thing they'll be complaining about if they drop the Nuclear ambition is 'Iran is spiking world oil with carcinogens.' -somebody sick and tired of hearing the word "anti-semite" everywhere.
MD5s won't help except to detect corruption, as you say in your first sentence. I imagine having duplicate copies of the DVD, recorded identically would be a cheap, low-tech alternative. Even if some blocks on one copy get destroyed, chances are those same blocks are good on another. With enough parallel copies, you can be sure to find a good version of each block on at least one.
While DVDs might only last a decade, it's not like they'll entirely go *poof* on day 3653. They'll begin degrading, but each one will degrade differently.
