Daniel Cohn-Bendit mentioned in the interview (look to the first post above) in the documentary film "Bye, bye blue sky" (Patrick Pasin) ( http://www.youtube.com/watch?v=ToxPiW_2RC8 ) about "military strategies" after being asked about the matter of chemtrails.
He did not explained what kind of "military strategies" they are.
According to the protocol of the "Open Mind Conference", Oslo 2012, Page 46 at least one strategy might be the hiding air traffic behind a fog of plasmas for the radarwaves or other electromagnetic radiation spectra which not only develop stealth quality to airplanes with radar-absorbing layers on their surface but obviously also to usual planes. This kind of strategy is quite the opposite of what it's called "Open Sky Policy":
"The chemtrail sprays have various elements in them like carbon which can used to absorb microwaves. Some of these sprays have metal flakes in them that make aerialcraft invisible to radar. Spoofer sprays. Sprays like these can be used to create colorful, magnetized plasmas to cloak fighter jets." http://baldron.org/wp-content/blogs.dir/4/files/2013/02/basrtio3_update.pdf
"The high levels of Ba stemmed from local quarrying for Ba ores and/or use of Ba in paper/foundry/welding/textile/oil and gas well related industries, as well as from the use of Ba as an atmospheric aerosol spray for enhancing/refracting the signalling of radio/radar waves along military jet flight paths, missile test ranges, etc." Purdey, Mark, Chronic barium intoxication disrupts sulphated proteoglycan synthesis: a hypothesis for the origins of multiple sclerosis in: Medical Hypotheses, Volume 62, Issue 5, May 2004, Pages 746-754 http://www.sciencedirect.com/science/article/pii/S0306987704000222

"Short article in Popular Mechanics on July 1996 announced existence of system called Variable Terrain Radio Parabolic Equation. In the article was stated that the VTRPE shows pilot what nearby radar systems can and cannot see under different terrain and atmospheric conditions using bands of different color generated by signal-curtaining inversion layers. At the time it was forecast that, because of high computing power requirements which are necessary to sustain needed real-time imagining, a cockpit-size system shall be available only within 10 years. If for chemtrail sprayings are applied cloud-seeding agents of metallic origin, as barium oxide is, then their continuous seeding, resulting in specific, low floating cloud ceiling which is electrically more conductive than the air bellow it, creates inversion layer allowing special radar signal reflection (similarly as ionosphere does with radio waves) which processed with sophisticated computing system could allow passive and active over-the-horizon radar capability.
Furthermore, such layer, as well as atmosphere below it, rich with barium hydroxide which is continuously precipitating from the bottom of the chemclouds, could be selectively energized with microwaves to inhibit operation of opposition's monitoring and targeting radars localy." http://www.deepspace4.com/pages/military/saipan/saipan1.htm

"Enemy Radar view
WRIGHT-PATTERSON AFB, OHIO - What could be more useful to a pilot than seeing what the enemy sees? Meteorologists of the 88th Weather Flight say their Variable Terrain Radio Parabolic Equation (VTRPE) could provide this rare view. A complex mathematical model that currently can run only on a supercomputer, VTRPE shows pilots what nearby radar systems can and cannot see under different terrain and atmospheric conditions. A cockpit-size system - available within 10 years - would show pilots how to hide behind signal-curtaining inversion layers." http://books.google.com.ua/books?id..._r&cad=0#v=onepage&q&f=false http://www.wpafb.af.mil/units/ http://www.wpafb.af.mil/units/oss/index.asp
Paris - Daniel Cohn-Bendit, deutsch-französischer Grünen-Politiker, will in drei Jahren aufhören: 'Ich möchte nicht, dass die Politik mich krank macht', sagte der 66-Jährige der französischen Zeitung Libération . Alles habe seine Zeit. Auch Respekt sei zeitlich begrenzt, das sehe er selbst an seinen Idolen. 'Bob Dylan war außergewöhnlich. Doch heute tourt er durch Vietnam und China, wo man ihm verbietet, "Blowin' in the Wind" zu singen. Unter diesen Umständen lohnt es sich nicht mehr, Bob Dylan zu sein.' Cohn-Bendit, der oft wegen seiner politischen Sprunghaftigkeit kritisiert wurde, bezeichnet sich selbst als 'liberaler Freidenker'." Süddeutsche Zeitung, April 16th/17th 2011, Page 10
"Cohn-Bendit wants to quit
Paris - Daniel Cohn-Bendit, green German-French politician wants to quit in three years: 'I don't want that politics makes me sick.' the sixtysix year old told the French newspaper Libération. Everything has its time. Also respect is timely limited. He sees that even at his idols. 'Bob Dylan was extraordinary. But today he is touring through Vietnam and China, where he is forbidden to sing "Blowin' in the Wind" Under these circumstances it is not worthwhile to be Bob Dylan.' Cohn-Bendit who often was criticized because of his political jumpiness describes himself as a 'liberal freethinker'." (Translated by Denglisch)
In case of quitting because of his unauthorized interview with members of the French Green Party shown in "Bye, Bye Blue Sky" it is sad, of course, that he quitted because of this interview. But in this regard the interests of public welfare are overwhelming compared to the injured respect to Daniel Cohn-Bendit. As members of parliaments (not only one single parliament) are also (not only governments employees) underlying obligations of secrecy it is a rare document as what elected representatives of the people are really thinking. If you study this interview carefully you notice that Cohn-Bendit felt with this topic incommodiously. Obviously, he was conscious himself that it has a high-level significance. The reason for this significance is still publicly unknown. Therefore nobody can comprehend why these programs are necessary.
The interests of public welfare occur because of the individual rights against the state (at least where this is written in the single constitutions of the countries) who - at least!!!!! - has the obligation to protect its citizens. And if he is not doing so the citizens have the right to protect themselves. But if the citizen doesn't have the knowledge about sky programs he or she is not able to do the best.
