Astronaut Eseoghene Obama when he tripped on a stone on the Moon, sending him flying
"These "people" are utter trash. Their entire culture has become some sort of insane thing where behavior that would put one in a mental hospital in any normal order. They deliberately give themselves mental illnesses and brain damage. They deserve to be eliminated from reality. Many have lost childhood friends to them. They target the edgy kids belonging to various weird subcultures, and slowly encourage their descent into insanity. I regret nothing when i supported Serbia and their Great Slavic Co-Prosperity Alliance, they have done nothing wrong. When i read their presidents' book depicting real events during the Collapse, i couldn't sleep for days. Luckily he managed to save many people from the clutches of insanity. The Perfect Order Party and their sister parties are the only ones in the world that i fully agree with." -Eric Trump
In 2038 (after the above-mentioned 2036 election win), aliens landed on Earth, namely in Eastern Europe distributed around Hungary, Serbia, Poland, Slovakia, Czechia, Romania. Even the far eastern corner of Germany (Bavarian Forest) got one ship, as well as Niederösterreich, not to mind Russia, northern Saskatchewan and Manitoba, and tropical areas in Benin, Gabon, southern Cameroon, Laos, Assam and Sumatra. This brought "collapse" not unto civilisation, but unto the affected regions. The species is silvicultural - and thus needs large tracts of forest - and looks somewhat like
Moropus, but armoured and armed to the teech with tech roughly 100 years ahead of ours. And the species is stronger and faster than us. Like Moropus, the aliens are carnivorous (but do need fruit and plant material from their native red plants to survive). They are out for a workforce of slaves (mixed with xenocide to the extent that is necessary for
QEZfINAM-tar'-forming the occupied territory), so basically colonial aliens!
They don't - as Trump Jr. claims - "give themselves mental illness" intentionally, but their brains and biologies are programmed to induce insanity (mostly in those already prone to it like "edgy kids", but sometimes also in totally sane individuals) in order to control the then-subjects better in order to use them to reshape and re-life the occupied territory. The Perfect Order Party of Dragutin Mladic captured a nuclear family of the aliens, put them in a high-security cell and tested on them until they found out that
Vitamin A1 (retinol) is deadly poisonous - and then Mladic and his cronies of the Greater Slavic Co-Prosperity League, to the applause of Trump, committed xenocide themselves! However, the damage was done and red plants grow alongside Earthly green ones in Eastern Europe, with animals native to both worlds competing in a radically changed ecosystem. But luckilly, some of the red plants are also edible to humans...
Except in Poland and East Germany, no aliens live anywhere from Plzen to Omsk or from Gdansk to Iraklion, however, sub-saharan Africa and parts of Southeast Asia are still plagued (or, as the aliens see it, could be made into a "safe homeland"). And much of Cameroon, Gabon and Biafra has indeed been totally transformed - red plants have outcompeted the green ones (with alien help) and animals native to their homeworld
QEZfINAM-tar' (colour is more important than the letter) have supplanted African fauna.
"Beware of native life when you step on another planet. You could destroy or infect it. So just look at the beautiful landscape and don't interfere with it!"
