Question: When was the region that lies to the north of where Israel is located and the location of Operation Earnest Will established?

Knowledge 1: Israel
Israel (/ ˈɪzreɪəl /; Hebrew: יִשְׂרָאֵל ‎, Arabic: إِسْرَائِيل ‎), officially the State of Israel (Hebrew: מְדִינַת יִשְׂרָאֵל ‎, Arabic: دَوْلَة إِسْرَائِيل ‎), is a country in the Middle East, on the southeastern shore of the Mediterranean Sea and the northern shore of the Red Sea. It has land borders with Lebanon to the north, Syria to the northeast, Jordan on the east, the Palestinian territories of the West Bank and Gaza Strip to the east and west, respectively, and Egypt to the southwest. The country contains geographically diverse features within its relatively small area. Israel's economy and technology center is Tel Aviv, while its seat of government and proclaimed capital is Jerusalem, although the state's sovereignty over East Jerusalem is not recognised internationally. The population of Israel was estimated in 2017 to be 8,777,580 people, of whom 74.7% were Jewish, 20.8% Arab and 4.5% others. [SEP] Knowledge 2: History of Saudi Arabia
For much of the region's history a patchwork of tribal rulers controlled most of the area. The Al Saud (the Saudi royal family) emerged as minor tribal rulers in Najd in central Arabia. From the mid-18th century, imbued with the religious zeal of the Wahhabi Islamic movement, they became aggressively expansionist. Over the following 150 years, the extent of the Al Saud territory fluctuated. However, between 1902 and 1927, the Al Saud leader, Abdulaziz, carried out a series of wars of conquest which resulted in his establishing the Kingdom of Saudi Arabia in 1930. [SEP] Knowledge 3: Geography of Saudi Arabia
The Kingdom of Saudi Arabia is a country situated in Southwest Asia, the largest country of Arabia, bordering the Persian Gulf and the Red Sea, north of Yemen. Its extensive coastlines on the Persian Gulf and Red Sea provide great leverage on shipping (especially crude oil) through the Persian Gulf and Suez Canal. The kingdom occupies 80% of the Arabian Peninsula. Most of the country's boundaries with the United Arab Emirates (UAE), Oman, and the Republic of Yemen (formerly two separate countries: the Yemen Arab Republic or North Yemen; and the People's Democratic Republic of Yemen or South Yemen) are undefined, so the exact size of the country remains unknown. The Saudi government estimate is at 2,217,949 square kilometres, while other reputable estimates vary between 2,149,690 and 2,240,000 sq. kilometres. Less than 1% of the total area is suitable for cultivation, and in the early 1990s, population distribution varied greatly among the towns of the eastern and western coastal areas, the densely populated interior oases, and the vast, almost empty deserts.

According to Bradley Peniston, the attack by the U.S. helped pressure Iran to agree to a ceasefire with Iraq later that summer, ending the eight-year conflict between the Persian Gulf neighbors.

The RCAF and Joint Task Force (North) (JTFN) also maintain at various points throughout Canada's northern region a chain of forward operating locations, each capable of supporting fighter operations. Elements of CF-18 squadrons periodically deploy to these airports for short training exercises or Arctic sovereignty patrols.
