Advantages that last for years thereafter
Every four years, countries compete ferociously for the privilege of hosting the Olympic Games. During those events, the entire planet focuses for a few days on the selected country, which gains not only increased stature in the eyes of the world but technological and financial advantages that last for years thereafter.
But playing temporary host to the Olympic Games pales in comparison to the honour and importance of permanently hosting the Embassy of the extraterrestrials!
Remember, only one country can be the site for this milestone historical event. Its resulting political, social, financial, historical and scientific advantages will not only last, but increase over time. People worldwide will forever look upon the host country as the leader of the Golden Age.
The country granting the necessary extraterritoriality and authorization for the embassy to be built within its territory will not only benefit financially but will enjoy the protection of the extraterrestrials. It will become the spiritual and scientific centre of the planet for millennia to come and happiness will prevail within its borders.
