In 1978 tensions continued to rise abroad. Spending on the military rose dramatically, and Jackson did not relent, but instead intensified, his buildup. Defying both concerns about the deficit and nuclear war, the President continued to build up the military further. His policy gained the support of many Americans, there was a widespread sense America had been losing its strength and they hoped Jackson could restore it. In the 1978 budget liberals attempted to cripple his buildup, but failed to muster enough votes. 1978 saw protests against Jackson's buildup that attracted media attention. Polls showed that a small majority of Americans supported his policy however, partly depending on how the question was worded. Negotiations over arms control remained dead. Tensions calmed in late 1978 temporarily, and due to concerns about the deficit President Jackson was forced to scale back part f his buildup. However military spending was still increasing, and the percentage of Americans that thought defense spending was too low was falling.
Scoop Jackson had throughout his career been a staunch supporter of Israel. As President, it was no different. There were hopes for a Middle East settlement between Israel and Egypt that could end, or at least reduce, the decades-long tensions in the region. Jackson was wary of such a settlement, viewing the Arabs as too much against Israel to reconcile the two sides. However, he decided he would be open to some negotiations between Israeli Prime Minister Menachem Begin and Egyptian President Anwar Sadat, to see where it went. However the result was impasse, with Begin refusing to concede Gaza or the West Bank, and negotiations stalled. Over the next year, the two countries would continue to work for a settlement. However US support declined to lukewarm at best, and hopes of a Middle East settlement fizzled out. Jackson blamed the failure of the Egyptians, saying they were "unreasonable and deluded" while many blamed Jackson himself and the Israelis.
Other foreign policy issues also seized the administration's attention. Africa saw several pressing issues. One was South Africa, and their apartheid system. There, the white minority used brutal force to enforce a system of racial segregation and inequality. Jackson and most Americans held apartheid in contempt. However in the administration there raged a fierce debate about whether to impose sanctions and apartheid, or whether South Africa was too much of an important partner against communism to undermine. Secretary of State Kirkpatrick argued that to undermine South Africa will "enable communism. They may be bad, but they're an important ally against communism, and that's the most important thing." Jackson was less certain, and found it unpalatable to support the repugnant apartheid system. He didn't have free maneuver on this issue, with a strong civil rights contingent in the party pressing for sanctions, and getting support from most Americans. The administration decided to criticize apartheid, with President Jackson declaring "The apartheid system is morally repugnant and wrong, and must come to an end." He refused to sell military equipment to South Africa and intensified economic sanctions, but did not go far as to ban the sale of civilian goods with a potential military use, or spare parts for said military equipment, leading to him being attacked as a hypocrite. However South Africa saw the US action as tough, it helped Prime Minister John Vorster win landslide re-election on anger with the US.
In Rhodesia, the President opposed the reimposition of sanctions. There, a white minority government was fighting off a black rebellion. In 1965 a UN resolution had imposed sanctions on Rhodesia, but in 1971 lawmakers had scrapped several sanctions on Rhodesia. Jackson instead sought to broker a solution in the country. The militant black Patriotic Front wanted immediate majority rule, but Prime Minister Ian Smith wanted a guarantee of white seats in parliament. Smith then established a new government with black ministers but enough white seats to prevent any constitutional changes. The PF denounced the plan and intensified its guerrilla war against the Rhodesian government. Jackson threw his support behind Smith's plan, viewing it as leading to black majority rule, and supported the effort to lift sanctions on Rhodesia.
Another foreign policy crisis the President faced was on the Horn of Africa. In 1974 Somalia had signed a treaty of friendship with the USSR, however three years later a Marxist-leaning military government came to power in Ethiopia and allied with the USSR too. However Somalia and Ethiopia were at odds. In 1977 Somalia invaded Ethiopia to claim the Ogaden region of Ethiopia. The Soviets tried to negotiate a settlement between its two client-states, but Somali dictator Siad Barre refused. The Soviets sided with Ethiopia, prompting Barre to switch sides and ally with the US. The Soviets then sent 12,000 Cuban soldiers and 1,500 Soviet advisers to Ethiopia to bring the conflict to a swift end. Jackson decided to intervene, despite the risks of increasing tensions between the two superpowers. Jackson declared his opposition to the Soviet involvement in the region, saying "I will not allow an unchecked spread of communism in the Horn of Africa. We will defend Somalia against communist aggression." Jackson sent an aircraft carrier to the Horn, and arms assistance to the Somalis, and threatened to use US airpower against the Ethiopians if they invaded Somalia.
The US made an offer to the Soviets. If the Soviets and the Cubans withdrew from the region, the US would no longer support Somalia, though would still threaten the use of airpower if Somalia's territorial integrity was threatened. Tensions rose in the region as the Soviets threatened to send more support to the Ethiopians. On February 25, 1978, the deal was reached, and the Cubans withdrew their presence from the Horn, and the US stopped supplying arms to the Somalis. The agreement was regarded as a triumph for the President, who ensured the Soviets could not have an active presence on the Horn, however some regarded his abandoning of Somalia as a fallback and betrayal. Now the superpowers had withdrawn from the fight. The Ethiopian forces attacked the town of Jijiga, but failed to get an easy capture. After weeks of protracted fighting, Jijiga fell to the Ethiopians. After a few more months of fighting most of the Ogaden was back in Ethiopian hands. The region saw low-level conflict and border clashes for years, but the war was widely regarded as a failure for Somalia, but not destabilizing to the Barre leadership.
