Due to Richard Nixon's absurdly big governing mandate, the White House pushed an aggressive agenda for 1972 and 1973. Universal health care had received previously been supported by a significant chunk of congress but had never been passed. Now, with cancer scares and increasing health costs, the government was ready to push it.
The American Health Act of 1973 (dubbed 'Nixoncare') would create a 'National Health Service', which would provide free health care for all American citizens and permanent residents. The act passed congress by a fair margin (273-154-8 and 54-40-6) and was signed by President Nixon in early March. Nixon also signed more sanctions on Russia (which at this point meant no American could do business with them) and encouraged trade with American allies instead.
Cases of racism and hate crimes against people of color in the United States actually went down, as a national camaraderie of 'heh at least were not those commies' was increasingly prevalent. On the other hand, many travelers from Russia were discriminated against. But the big news in America was the changing foreign relations. Because of the war, plenty of countries were moving towards America and away from Russia. Congress approved an additional $10 Billion in aid to those countries for the sake of 'national defense'.
Many communist countries not stuck to the USSR for economic or military reasons adopted a more Yugoslavian style of foreign affairs, opening up relations and trade with the west. These countries included Albania and North Vietnam, along with many African countries. But foreign affairs wasn't at the forefront of the Nixon administration's policy.
In the aftermath of the Sino-Soviet war, the defense budget was greatly changed. The total amount didn't go up much, but the recipients did. Funding for ground troops and vehicles was cut, with over 50% of ground forces being mustered out or retrained. Most of the newly freed-up money went to the anti-ICBM program and various aircraft programs, particularly in the field of interceptors and multirole fighters.
The anti-ICBM program, or the High-Altitude Intercontinental Ballistic Missile Interception System, was started in 1971 following the war. The program's two stages were a satellite network for tracking and a supersonic attack vehicle. The attack vehicle was attached to a missile and was relatively cheap. Testing was promising and 1 Satellite and 50 missiles were in place by the end of 1973.
But the most exciting things that were happening in America had to do with the space program. Previously, the Apollo program was going to be canceled after Apollo 17, but following the nuclear war some genius in P.R. decided that showcasing that America was doing good things with rockets and missiles could increase the international reputation of the country. Apollo 18, 19 and 20 were launched in 1973, with Apollo 21 scheduled for early 1974.
Things were looking up for America.
