3: A good amount aside from the nuke.
Explanation
World War 2 is the most costly war in the history of mankind with websites estimating total loses worldwide between 60 and 120 million lives lost including soldiers, civilians, and prisoners. Germany and Russia caused WWII on September 1, 1939 when both nations invaded Poland from both sides, Russia with overwhelming force, and Germany with their new Blitzkrieg strategy. Some technology that was invented that are rarely mentioned are the use of air systems and parachutes for aircraft first being used in combat, Thruster powered aircraft (Jets), and a recoil operated muzzle booster that helped make the MG 42, (aka Hitlers Buzz Saw) the most dangerous firearm to fight against. This mechanism paved the way for how firearms are made today with an average RPM, (Rounds Per Minute) rate for the MG 42 at a jaw dropping 1,200-1,600 RPM, over twice the fire rate as the American M1919 at only 400-600 RPM. Hope this helps.
The correct answer is - United States.
The United States are a country that has a very large population that speaks the Spanish language. This is due to two factors, the conquering of some of the Mexican territories, and the migration from countries that are Spanish speaking countries.
When the United States managed to conquer Texas, New Mexico, Arizona, California, most of the population living there was a population that was speaking Spanish. Even though new settlers came, and lot of time has passed since then, the people retained their languages and still speak it.
The big migration from the Spanish speaking countries south of the United States has resulted in an ever growing Spanish speaking population in the country. Taken in consideration that the Spanish speakers actually have the highest birth rates in the United States, the number will only increase over time.
