much shorter.

much longer.

less dangerous.

more dangerous.

The correct answer is "much shorter".

The First World War was a military conflict that initially involved the countries of Germany, Italy, and Austria-Hungary, which formed the "Triple Entente" against Britain, France, and Russia, which formed the "Triple Alliance". The War went through 1914 until the latter part of 1918.

The United States had remained neutral in the War. However, the sinking of American merchant ships by German Forces in 1917 prompted the country to enter War. American involvement would include the sending of nearly 2 million troops to the combat zones and continue until the end of the war on November 11th, 1918.

on this day in 1939, in response to hitler’s invasion of poland, britain and france, both allies of the overrun nation declare war on germany.

the first casualty of that declaration was not german—but the british ocean liner athenia, which was sunk by a german u-30 submarine that had assumed the liner was armed and belligerent. there were more than 1,100 passengers on board, 112 of whom lost their lives. of those, 28 were americans, but president roosevelt was unfazed by the tragedy, declaring that no one was to “thoughtlessly or falsely talk of america sending its armies to european fields.” the united states would remain neutral.

as for britain’s response, it was initially no more than the dropping of anti-nazi propaganda leaflets—13 tons of them—over germany. they would begin bombing german ships on september 4, suffering significant losses. they were also working under orders not to harm german civilians. the german military, of course, had no such restrictions. france would begin an offensive against germany’s western border two weeks later. their effort was weakened by a narrow 90-mile window leading to the german front, enclosed by the borders of luxembourg and belgium—both neutral countries. the germans mined the passage, stalling the french offensive.
