Explain why modern wars are often less deadly and destructive than ww1 was.

Geneva convention/Laws of war

Explanation:

WW1 Didn't really have any rules when it came to war thus there were cruel weapons and tactics used causing many deaths on both sides of the war but in modern times there are many things that change the way you have to fight, such as ROE(Rules of Engagement) and certain ammo types must be used because the collateral damage they have is lessened compared to other rounds. Also technology has changed a lot since then, body armor, armored vehicles, and advancement in weapon technology making engagement distances far greater.

answer: secession

secession, as it applies to the outbreak of the american civil war, comprises the series of events that began on december 20, 1860, and extended through june 8 of the next year when eleven states in the lower and upper south severed their ties with the union. the first seven seceding states of the lower south set up a provisional government at montgomery, alabama. after hostilities began at fort sumter in charleston harbor on april 12, 1861, the border states of virginia, arkansas, tennessee, and north carolina joined the new government, which then moved its capital to richmond, virginia. the union was thus divided approximately on geographic lines. twenty-one northern and border states retained the style and title of the united states, while the eleven slave states adopted the nomenclature of the confederate states of america.
