>I've always wondered why UFOs are only a USA phenomenon
It plain isn't and to claim that it is shows that you have done EXACTLY 0 research into the topic. This kind of bad faith engagement shows an utter lack of curiosity.
UFOs are huge in South America within just seconds you can find hundreds of sightings and discussions about them:
Must I go on or is that enough to accept that "UNKNOWN THING IN SKY DOES WEIRD THING I DON'T UNDERSTAND" is pretty much a global phenomenon that can and should be scientifically investigated just the same as we would investigate everything else we find anomalous?
This doesn't prove it's aliens. It does add to my mass-hysteria hypothesis. I want to see the biological remains firsthand in Zimbabwe, Japan, etc. I want to see the crater the UFO left on the ground. I want to see the craft. Where's the physical evidence? Not photos, actual dirt displaced, metal alloy, extraterrestrial biological remains, etc.
I have no dog in this fight, but I want to ask a question.
What are your thoughts about multiple pilots in formation seeing things that are corroborated by optical, laser, and radar sensors used by the local aircraft and remote radar platforms?

You don't notice it do you? Re-read again what I wrote. At no point did I argue that it's aliens. Intentionally.
You first point was proven wrong instantly "it's only an USA Phenomenon". You don't bother to research anything but stick with your hypothesis. You don't even go look for evidence yet are utterly convinced of the result of your complete lack of research.
Here's an example of metal alloy that's supposed to come from an UFO and shows an interesting composition we cannot replicate. It's a well known artefact:

Ufos are also a thing above Europe with the Belgian Ufo wave and the Rendlesham Forest incident being well known and seminal cases in UFO Lore

Africa also had for example the ariel school incident in Zimbabwe, one of the most well known UFO cases ever

Same goes for russia where after the cold war ufo sightings were discussed in offically declassified documents:
