well I have heard that as well, that they have attempted to change the weather at certain important events, I still highly doubt that we have any significant influence on the weather, weather systems are hundreds of miles wide, I can believe they could have an effect on a small portion. I stand corrected 😃https://www.google.nl/amp/s/www.thesun.co.uk/news/2693382/china-is-controlling-the-weather-and-will-soon-make-it-rain-over-an-area-twice-the-size-of-france/amp/
I agree they could do evil stuff with this, our only hope is that international treaties and law make sure that all countries keep to the pact of not using chemical weapons.

I think most governments agree that using chemical weapons is a bad idea in any form, as it will put anyone in danger.

I mean China controls people through their new bear system, they are not particulary hiding it. Through the use of big brother they control the behaviour of the population.
Satellites can pick up on certain particles in the air, so I think keeping secrets becomes more difficuly every day.

What can we do? Get rid of central banking systems and move the power of money into a decentralized fashion. A lot of evil is driven through our current financial system.

I believe crypto coukd deliver a better system in the future. Perhaps in dit's current form, it solved the centralized trust issue that we needed banks for.

People need to still grasp that fact, spreading this word is more important than anything else imo.
