[David Attenborough voice] Here we see the Yankee attempt to protect their bubble by claiming that anything which contradicts their perceived reality is the result of some dangerous foreigner.

However, while the Yankee does their best to isolate themselves from the perceived dangers outside, they are completely unaware that this paranoia is just one of the symptoms of the parasite that has begun to lodge itself deep within their brain. Without immediate assistance the Yankee will likely develop increasingly fascist tendencies before perishing in a rather gruesome manner as the Yankee colony self destructs.
