1) Leak news stories in the tabloids about talking parrot spies who have been given a secret new "IQ Serum". Have actual "secret labs" set up where people answer the phone and say "no comment" before hanging up. Supply pictures and interviews with animal trainers and biochemists. Say that the birds have been trained to make phone calls and place reports. Have pictures of the birds with coins operating pay-phones!
2) Have telephone-psychics announce impending attacks on live TV so that troops are moving to intercept at the same time the public is taking cover.
3) Scatter the sensors on phone and electric towers throughout the country. Put them right by the light on top. Call it a bird deterrent. Telephone modems existed in the 80's, so the technology could be used to transmit sensor data. Have some poor family go one the local news and talk about how accumulated bird droppings on powerlines caused a fire that severely injured or killed family members. Make a story that has everyone crying. Protest groups in the local town make the devices mandatory for power lines near houses (data processing centers). Start a nation-wide movement where the government RELUCTANTLY pays for them in the interest of public safety. AS LONG AS it looks like they DID NOT want to do it, but the people insisted.
4) Return to the tabloids and say that the government has been receiving signals from a friendly alien race.
5) Invent an 80s version of Snowden, and have everyone believe he lives in the enemy country, as a high-ranking member of their government. Have weekly press releases from pirate radio stations replaying the frantic warning calls (that never actually happened) to your countries police stations. It will be an underground hit bigger than "Rescue 911".
6) Have the tabloids release pictures of the new "Electro-Glass Microphones" that the government has been putting on kites and clear weather balloons, that are "ALMOST invisible". Say they are transmitting on certain frequencies, and release balloons occasionally that interfere with TV and radio broadcasts. Have reports of them crash-landing on people's houses every few weeks. Have the whole town shut down while the military "recovers" the small almost invisible technology with their "invisi-glass detector gear". Let the enemy hear rumors about how this glass has a slight metallic content, and highly radioactive beams from a concentrated source make the parts visible on XRay film. Have a two or three hour buildup of military forces before the town is locked down for the search. Publicly scrutinize the military for taking so long to lock it down. Hint that the technology could easily fall into the wrong hands. Use the time window to trick spies into searching for non-existent parts to recover, and capture spies. Interrogate spies on what they know about unreal technology for several weeks before allowing a single STUPID spy to escape during a prisoner transfer, or a mass-escape from the facility by other "prisoners" who are actually special ops troops who help the spy return to their own country.
Monitor theft of xray film and report on the news that xyz film company has been robbed 6 times this week.. to attract more spies looking for equipment. Any stolen radioactive material would be easy to spot from the air. Leaked faulty plans for scanning equipment means that spies trying to use the equipment will be dosing themselves during the search, shortening their effective lifespan as enemy agents. The enemy will have lots of good agents give their lives to acquire something that does not exist.
7) Report that enemy planes are known to vibrate at certain frequencies that effect moisture in the atmosphere. Say that you can use beams of light at night to scan the sky and see the vibrations. or that looking at stars allows you to see the vibrations as the light wavers. The enemy will have to rebuild their entire airforce two or three times to get the planes to "vibrate differently". Say that the sheer volume of the vibration causes these waves over 3/4 of a mile. Also point out that civilian telescopes and those at universities are NOT properly focused to see the effects. This will keep them from becoming terrorist targets. It will also make the enemy frustrated trying to figure out the optics behind it, as no known telescope available to them is capable of seeing it, so they have no way of knowing if their new designs will work or not.
8) Ask at UN conferences for ALL allied countries to send us their BEST entomologists! Ask specifically for ones that have a background in long-range radio communications. Ask for any research information on radio frequencies that may or may not effect mosquitos and their reproductive cycle. Ask about mosquito breeds that are resistant to insecticides, and anyone who has an immunology background pertaining to flying insects. Ask for experts who may have placed radio transmitters on mosquitos, or have used radar to track swarms of them. Ask for bug-intellect studies when exposed to high levels of focused microwave radio beams. Ask for REALLY weird bugs and radio related intel and personnel. THEN START A MASSIVE COVER-UP! Burn the labs and all the research. Report scientists kidnapped or killed. All of the FAKE scientist who the govt has been sending abroad should cease to exist. Deny ever knowing them. Deny they ever lived. Burn the record offices in their supposed hometowns.. or just that one file cabinet... Deny the conversations took place at the UN meetings. SOMEONE, SOMEWHERE will start leaking information about your country's attempt to use large swarms of radio transmitting mosquitos... and the enemy nation will create an insecticide or bug virus to rid your country of mosquitos for you.
9) Report that an enemy pilot called his mother before the mission, and the call was intercepted.
10) Report in the tabloids that UNNAMED members of the royal family, or ruling party of the other country secretly want to come to your country because they like one particular type of food that their country does not have. Report that their craving for this food is so strong that they trade battle plans with your govt for just a taste of it. The secret police of the other country will constantly follow their own leaders trying to discover the mole. (DO NOT name the type of food!)
11) Report that emissions from enemy fuel leave trail in the sky that are visible on spectrograph over long distances. Emissions from jets, bombers, and even submarines are equally visible. (This can even be a follow-up for scenario number seven!) Have one of your best scientist who was working on low-emission fuel leave the country for tax evasion. Have them hide in a country that has ties with your enemy, have them seek employment and wait to be recruited. Have your scientist work WITH the enemy to create low emission fuels, which will benefit the entire world once the info is leaked. Let them use a HUGE CHUNK of their military budget to do the research and testing.
