What was the global significance of the cold war?

Answers

Answer:

Explanation:

The cold war showed the divide between capitalism and communism and overall showed how the world war divided. It even left every country vulnerable as if one nuke were ever to set off, the other country would counter-attack with their own nukes POSSIBLY causing an extinction event. This is called M.A.D or mutually assured destruction where if one country fires a nuke onto another, the other country will counter attack with nukes which will cause all-out destruction.

Overall, the main significance was the danger it posed to the 2 superpowers with completely opposing ideologies which dragged pretty much every other country with them. It even showed that war was no longer a possibility nowadays because if any of the superpowers were to go to war, nukes would be used to utterly destroy the other. So they had to avoid a direct war at all cost.

What do you know about World War II ?

World War II, sometimes known as the Second World War or simply WW2, was a global struggle that lasted from 1939 to 1945. The vast majority of nations in the world, including all of the major powers, participated in the war as members of the Allies and the Axis, two military coalitions that opposed one another.

The line between civilian and military resources became fuzzier as more participants poured their economic, industrial, and scientific resources into this all-out conflict. The only two nuclear weapons ever used in combat were delivered by aircraft, allowing for the strategic targeting of urban areas. With 70 to 85 million fatalities, largely civilians, World War II was by far the bloodiest conflict in recorded human history. Genocides caused tens of millions of deaths.

Explain why the Western Roman Empire fell/collapsed. Use at least three reasons/causes. Please use full sentences

Doesn’t have to be super long but will give brainly and extra points! Thank you!!

Answers

Answer:

The fall of the Western Roman Empire can be attributed to the string of military losses the empire faced such as against the surrounding Germanic tribes, the Visigoths (who sacked Rome in 410). Another rationale can be due to political instability and corruption as the leaders as many factions including the Praetorian guard who were supposed to protect the emperor had been assassinating many and placing new sovreigns at will which led to large power vacuums and instability leading to distrust from the citizens. The third rationale can be due to the weakening of the Roman legions through the use of foreign mercenaries which tend to be unloyal to the empire leading to a overall weakened force.  

Explanation:

It all resulted in the barbarian tribes attack
The empire city was raided in 455 by the vandals Finally, in 476, the Germanic leader Odoacer staged a revolt and deposed the Emperor Romulus Augustulus

The Constitution calls for representatives to serve fewer people than senators, so they can address the needs of individual constituents. The Constitution allows constituents to remove a representative by majority vote within the first six months of that representative's term. The Constitution gives representatives a shorter term of service than senators so that the House will be more responsive to current issues. The Constitution limits the number of terms a representative can serve, so people can frequently choose new representation.

D-DAY LANDING

The D-Day landing was in a nutshell, the Normandy landing, where many soldiers from many countries like Canada, Britain and America secured a beachhead for a springboard to free France from Nazi rule. One of its main purposes was to create another front, stressing and stretching the capabilities of the Nazi soldiers.

==================================================================

HOW DID IT HELP ALLIES WIN?

This created a new front which further put less stress on the Soviets as the Nazis had to move troops to Normandy just to stop their advances. This also created a new front meaning they were being attacked not from 2 fronts but 3 fronts which were from the Soviets, Sicily and France. This was seen as a huge turning point of the war as Nazis started losing land in mainland Europe from ALL SIDES. It was to the point where both the Soviets and the British/American/French were advancing into core German lands.
