At one point, it was a threat.
Think of the Cuban Missile Crisis.
Cuba was a vassal state of the USSR and was considered a springboard for communist takeover of Latin America.
Well, those days are over...
I really don't know what's going on now. Cuba is still in cahoots with Russia. (It is believed that Russia did that sonic thing about 10 years ago) https://en.wikipedia.org/wiki/Havana_syndrome
Anonymous sources claimed that Homeland Security Investigations purchased a device in an undercover operation for millions of dollars toward the end of the Biden administration. The backpack-sized device is said to emit pulsed radio frequencies.[156] Testing is ongoing and some are skeptical that this device could be the cause of Havana syndrome.[157]
According to CBS, "[t]he device is portable, backpack-sized, and contains components of Russian origin".[156] In March 2026, a 60 Minutes report further described the weapon:[158]
It doesn't look anything like a gun. It is designed to be concealed and small enough to be carried by a person. It is silent and doesn't create heat like a microwave oven. Our sources say the device is programmable for different scenarios and can be operated by remote control. The range of the beam is several hundred feet. It can penetrate windows and drywall. The vital components were made in Russia. Our sources say the key is not the hardware but the software. The programming shapes a unique, electromagnetic wave that rises and falls abruptly and pulses rapidly.[158]
