Okay, The United States and the Tropical Roman Empire have diplomatic relations at the level of the Eastern Roman Empire with the Holy Roman Empire, which are terrible and have been tense since the end of World War II.
Diplomatic relations between the two powers were cordial, after all the Tropical Roman Empire had supported the independence of the Thirteen Colonies, there were small incidents such as The Pacific Crisis in 1875, where the American Navy bombarded a Roman-tropical merchant ship, thinking it was a pirate ship, Emperor Titus I threatened the United States with a rebellion of the states that belonged to Mexico until 1848,President Ulysses S Grant, hero of the Civil War, met with Emperor Titus I at the White House and after a few hours of intense discussion the Treaty of Washington was established in December 1875, established the zone of Roman-tropical and American influence, this was the first incident between Washington and Augustopolis, after that in the mandate of Theodore Roosevelt with his Big Stick policy, he tried to demonstrate that the United States would be the de facto power of the New World, so in 1907 the Luciusville Incident occurred, 5 battleships USS Oregon and 3 cruisers USS Olympia invaded Roman-tropical waters, in return the Tropical Roman Empire sent 2 battleships Claudius V, 3 cruisers Julius Favarus, 4 Fabius Maximus class submarines, the confrontation lasted about 5 hours and the United States lost 3 battleships USS Oregon and 2 cruisers USS Olympia, with this incident, diplomatic relations between the United States and the Tropical Roman Empire were ceased for about five months until in Cuba, President Theodore Roosevelt and Titus I made the Treaty of Havana which delimits a new zone of influence between Washington and Augustopolis, so this incident was forgotten in American naval history as the equivalent of the Battle of Cartagena de Las Indias, for years the The event was portrayed as an attack by American ultra-nationalists and opponents of the Democratic Party who were trying to destroy diplomatic relations between Washington and Augustopolis.
But nothing compares to the first years after World War II, in 1948, To the surprise of the United States and the Soviet Union, Emperor Titus II at the Palace of Nova Florentia reported to the entire world that the Tropical Roman Empire had its own atomic bomb, the Lux aurorae, President Harry S. Truman wrote a letter to the U.S. Army and Navy about a "Fourth Axis" and how the Tropical Roman Empire was openly defying Washington, in the Soviet Union, Stalin spoke about "Roman-tropical fascism" and how the American continent was dominated by American and Roman-tropical imperialism and the "liberation of the proletariat Latin American", in response to the Americans and Soviets, Titus II issued the Edict Dominus Lucis, The Edict marked the official position of the Tropical Roman Empire on the use of atomic energy and on which occasions the Tropical Roman Empire would use atomic bombs.
During the reign of Titus III in the 50s and 60s, the Tropical Roman Empire expanded its nuclear arsenal and in 1968, the Tropical Roman Empire showed the world the Flagellum Crepusculi, the first Roman-tropical hydrogen bomb, President Lindon B Jhonson spoke about "An enemy that masqueraded as an American ally in both world wars and proved to be as dangerous as the Soviet Union", in the Soviet Union, Leonid Breznhev spoke about "the last stand of monarchist imperialism" and "the oppressor of the South American proletariat", my great-grandfather Emperor Titus III, in a speech at At the Augustopolis Forum, with the tribunes and tribunes plus elected in the 1967 election, in his speech he not only confronted the Americans but also the Soviets, delivering one of his most famous speeches.
"As long as the United States and the Soviet Union carry out coups d'état in Africa and Asia, that doesn't matter to us, but if they try to impose an American or Soviet puppet state on our borders, You will see why the royal heirs of Latium survived cataclysmic events: the Portuguese conquest, the sack of Augustopolis in 1745 and the Crisis of the 19th century. We don't care about your proxy wars, but never doubt what we can do. You may have NATO and the Warsaw Pact, but we have heroes like Scipio Africanus, Julius Caesar, Octavian Augustus, Marcus Aurelius, Trajan, Aurelian, Constantine the Great, Flavius Aetius, Majorian, Claudius V, Justinian the Great, Flavius Belisarius,Fabius Licinius, Honorius Marcus, Julius Favarus, Fabius Maximus (early 19th century), Titus I, if Washington or Moscow wants to confront the heirs of Latium, know that we will be ready to show the strength of Roman civilization."
Fragment of the speech "Response to Washington and Moscow" , 15/06/1968, Nova Florentia Palace, Augustopolis.
It had been about two weeks since the Saturnians had given a "scare" to the military and economic powers, since then they have been more attentive to the space threat.
I was finishing reading the biography of the Roman-Tropical Chancellor Stephanus Farias Lucas, first Tropical Roman Chancellor from 1945 until 1950, notably the Tropical Roman Empire prevented the Soviet Union from invading Austria in 1948 by threatening to support the Finns in to recapture Karelia from the Soviets, when the maid came to my room and said.
"Your Highness, Empress Flavia is calling you to dinner."
I got up from bed and told the maid.
"You can get out of here Gertrudes, I'll go there."
I went downstairs, outside it was raining heavily, the employees were scared by something, but they didn't want to say what it was, my grandmother with her Sicilian accent ordered calmly.
"Sit down, my grandson, I will have to tell you about your great-uncle, Prince Paulus."
My grandmother clapped her hands and the employees left, then she explained what was happening.
"Your great-uncle Paulus Libius Carolus is somewhere in Russia right now, gathering Russian army forces, our forces indicate that in three weeks, in the city of Arica, a rebel force will arrive in our Roman-tropical waters, but it seems they will invade the port city of Callao as their real objective, because of the terrorist attack in Madrid, your great-uncle got support from the Russian military and covertly from Putin himself."
I see that someone who sees the Russians as eager for a fight between nuclear powers, this will certainly disrupt Putin's plans in Donetsk and Luhansk, the world is not prepared for the chaotic 20th decade of the 21st century and if someone tries to anticipate it, the Saturnian kingdoms are capable of conquering the entire planet as if they were the Zulus facing the English, a fight that no power Earth can face the interplanetary threats that the 21st century awaits and if the Russians want this, the Saturnian kingdoms will thank them for their efforts in destroying any human resistance.
"Your grandfather is currently leaving by bullet train from Augustopolis to Antofagasta, military personnel from the Pacific region are waiting for him, everything will depend on his reaction as to whether he will consider this a reason to use the Edict Dominus Lucis or not."
I hope my grandfather simply doesn't drop atomic bombs on Russia, Chile and Argentina would become uninhabitable places, Ecuador, Colombia, Venezuela, would suffer from gigantic radiation, besides, if the United States has problems with illegal immigration, this would practically be a Crisis of the 5th century, millions of Latinos fleeing the dust of the gigantic radiation of South America, definitely this would be the end of any attempt to survive the chaotic 21st century, Saturnian kingdoms trying to contain any Earth expansion into the solar system, for now I'm just a 15 year old boy if I talk about very futuristic technologies like miniaturized tanks, they would call me crazy or I'm reading too many comics, so I have to wait at least until I'm 18 to try to influence the navy and army for future problems and found the Roman space force, I trust in you, Roman-tropical Emperor Titus IV, Imperator Romanus-tropicalis, Restaurator Mundi, Dominus Atomi, Praefectus Supremus Peruviae, Peruviae Superioris, Novae Syracusarum, Perpetuus defensor Latium.
Good luck grandpa, the fate of the Earth is in your hands.
