Which of Reagan's policies do you feel was most successful and why?

Answers

foreign policy, it was the best policy beacuse it was for winning the cold war

Of all the various policies adopted by President Ronald Regan, the policy which was most successful was the foreign policy. It was the best policy because it was for winning the Cold War.

What was included in Reagan's foreign policy?

The prevention of communist spread in the world was at the centre of Reagan's foreign policy. This was proven by the United States' substantial financial and military support for the Contras against the communist Nicaraguan government, as well as aid to the government of El Salvador in their struggle against the communist guerrillas. This collaborative effort was dubbed "The Reagan Doctrine."

Reagan believed that the United States should approach the Soviet Union from a position of strength. To that purpose, the administration launched a strategic modernization programme that included the development of an intercontinental missile, a stronger fleet, and a feasibility assessment for the Strategic Defence Initiative.

This passage, from the Anglo-Saxon Chronicle, tells about a Viking raid on the English region known as East Anglia.

1010. After Easter this year the Viking army we spoke of before came to East Anglia. They landed at Ipswich and marched straight to where they had heard [the lord] was with his local forces . . . And the East Anglians ran off at once . . . The Danes held the battlefield. Then they got horses and afterwards took control of East Anglia, and plundered and burned the countryside for four months - they even went as far as the wild fens and killed men and beasts and set fires throughout the fens, and burned down Thetford and Cambridge and then turned south to the Thames . . . Then they turned back to their ships with their plunder. As they were going to their ships, the English army should have come back into the field to prevent them turning inland again. And that's when the English army went home . . . [A]ll the council was summoned to the king to determine how to defend the realm. But whatever was decided on did not last even a month. In the end, there was no leading man who was prepared to call up his forces. Everyone ran off and did the best he could.

Why were the English unsuccessful in launching an attack against the Vikings?

They did not have enough weapons to attack.
They were too outnumbered to defend themselves.
They could not agree on how to best defend the region.
They decided to negotiate instead.

One result of the Sepoy Mutiny was that?
Select one:
O a. The British East India Company went bankrupt.
O b. The British government tightened its control over India.
O c. The British stopped trying to convert Indians to Christianity.
O d. British officials became more sensitive to the needs of Indians.

Answers

Answer:

O b. The British government tightened its control over India.

Explanation:

The 1857 Sepoy Mutiny or the Indian Mutiny was the unsuccessful revolt of the Indians against the British regime. This revolt was also known as the first war of Independence, resulting in the bloody and violent loss for the Indian troops.

The Indians were unhappy to be under the Britishers. With different approaches to try to get their liberty, the people would rebel against the empire. One such event is the Sepoy Mutiny where the 'hired' Indians were unhappy about the many issues, be it racial discrimination, religious disregard, low pay, etc. Though the revolt started with the issue of how to grease their guns (with animal fat) which was great against the religious beliefs of the Hindu and Muslim Indians, it would only lead to a bloody encounter and was successfully quelled by the Britishers. This event led the British government to tighten or restrict the freedom and rights enjoyed by the Indians.

Thus, the correct answer is option b.

Answers

Each candidate had a solid regional base, but none had the support of all regions.

The Whigs selected William Henry Harrison to run against President van Buren in the campaign the Whigs compare Harrison due to his similar ideas & views.

Why was William Henry Harrison selected by Whigs?

The Whigs painted a negative picture of Van Buren despite the fact that he was born into poverty; they painted him as an aristocrat and a collector of expensive goods. This increased hostility to President Van Buren's efforts to control the 1837 economic Panic, which had led to numerous bank failures and significant unemployment.

Because William Henry Harrison had traits with past president Andrew Jackson, including being a war hero and a man of the people, the Whigs decided to support him.

Furthermore they bombarded the electorate with signs and stickers praising their vibrant, wholesome "log cabin and hard cider" candidate, the Tippecanoe hero. The Whigs misrepresented Harrison to the electorate by altering his image.

Thus Whigs selected William Henry Harrison to run against President van Buren.

Why was fascism opposed to socialism? To democracy? To liberalism? What was the fascist alternative, according to Mussolini? What were the principles and goals of a fascist state?

Answers

Answer:

fascism is a left wing party while socialism is a right wing party and they usually never agree on one thing and from history, they mostly fought it out in wars/street battles. the fascist alternative according with Mussolini was meant to make the nation a strong place while reforming the greatness of said country and Mussolini's Fascism was Imperialistic to go along with reforming the greatness of Italy seen by the annexation of Ethiopia.

Fascism attacked socialism in large part because it disagreed with its emphasis on class conflict and wealth redistribution.

Democracy was rejected by fascism because it was seen as a feeble and ineffectual form of government. Fascist philosophy opposed political pluralism and individual liberties and placed a high emphasis on centralized leadership.

Liberalism's emphasis on individual rights, minimal government intrusion, and free markets was opposed by fascism. Fascists held the opinion that such ideals promoted individualism at the expense of societal cohesion and popular will.

The formation of a totalitarian state that combined authoritarian leadership with corporatist economic principles, according to Benito Mussolini, was the fascist alternative.

The principles and goals of a fascist state included: Authoritarian Leadership; Nationalism; Totalitarianism; Corporatism, Militarism and Expansionism.

Extreme nationalism was encouraged by fascism, which also aimed to preserve and elevate the country's past and culture. The importance of the nation and its unity over personal interests was highlighted.
