1. He inherited a full-on war 10,000, miles away which pitted us against about 2,000,000 enemy fighters (VC and NVA), fully and lavishly supported by the Soviets, the Chinese, the Warsaw Pact, and some slimy "allies" of ours too. Remember too, that the pro-enemy "antiwar" movement was gathering tens of thousands of dimwits to obstruct the conduct of the war - including carrying enemy flags. (I'd love to have seen these jerks pull that crap during the WWII!)
2. He inherited the major part of the Civil Rights mayhem, immediately after Martin Luther King was assassinated and most major cities had burned - and the huge expenses of LBJ's War Against Poverty.
3. We had to maintain a huge Cold War force in Europe and Japan, plus bombers and missiles on standby - all expensive, in manpower and supporting costs.
4. In the Middle East, a major war erupted between Syria, Iraq, and Egypt against Israel that was a really close-run thing, also inflamed by Soviet meddling and support in the Arab countries (including offering nukes to Egypt). We also had the Arab Oil Embargo going, which drastically affected out country/
5. Then, we had a the "Space Race", including the very costly and risky "Race to the Moon" which Kennedy had started and had already cost Billions.
Nixon was an outstanding President who, like Trump, never had a break from the press for a single second - yet. like Trump, worked miracles to keep our country safe and away from the brink of Armageddon.
I will always despise the Left and the Democrat Party for what they did to Nixon and Trump.
Nixon put the Great Society on steroids , and began the sell out to the chi-coms. I would have voted for John G Scbmitz in 1972.
That idiot also took us off the Gold Standard, and devalued the dollar.
