Do you think we could discourage illegal immigration by buying TV ads in the countries where the migrants are coming from that scare them into not coming to the US?

Ads like "you have a 50% chance of dying in the desert if you come" or "your daughters will be raped in Joe Biden's detention camps". Ads that basically point out all the negatives of coming to the US and all of the dangers.

Do you think that the ads would be expensive? Would they be effective? Would the foreign TV networks air them? We would need someone to make the ads and narrate them in Spanish. Not sure what medium is most prevalent in those countries, whether it is Internet, TV or radio, but what if we drove home the point that coming to the US is dangerous and not worth the risk.
