Answer:
2 nd one is the answer yess
The answer is (b.) the first gulf war
The first gulf war is between the coalition forces led by the US against Iraq. It is also know as Persian gulf war, Kuwait war, first Iraq war, or Iraq war. It started on August 2, 1990 and ended on February 28, 1991. While the six-day war is the conflict between Israel and Egypt in 1967 and Yom Kippur War in 1973.
A major problem for the United States after the Revolutionary War (1775-1783) was that tens of thousands of Loyalists, due to the climate of violence and fear that still existed after the conflict (particularly in the South), fled the country, retreating with the British army to Britain and other parts of the British Empire (Jamaica, Bahamas, India) and also to Canada, settling primarily in the regions of Nova Scotia and New Brunswick. Since those Loyalists were often wealthy and educated, and they had been part of the thriving and cohesive upper class that controlled much of the industry and the commerce in areas such as New York or Boston, the social structure of the colonies changed significantly after their departure.
