Starting in 1823, the US tried to claim all the Western Hemisphere as a US neo-colony. Of course, in 1823, the US was too weak to challenge the UK outside the US, and had barely managed to get the UK to stop conscripting US citizens as sailors for the UK fleet in 1814. But, thanks to high tariffs, which the US called 'fair trade' as opposed to letting the UK flood US markets for manufactured products with what the UK called 'free trade', US industry was growing, slowly but steadily. So the US Navy was also growing, and by 1900, was at parity with the UK Navy.
By the 20th century, much of Latin America were US neo-colonies, with the US giving a small group lots of weapons and enough money they were happy to take over the government of their own country and then do whatever the US asked them to do, the most famous of which was providing the US with lots of very, very cheap bananas that were sold as cheap bananas in the US and still made the neo-Imperialist American banana importers rich. If one reads Ayn Rand, she also talks about the US getting lots of Latin American copper very cheaply, at great profit to the American companies that mined the copper, paying the Latin American labourers minimal wages (but decent payments to the citizens of the country who were running the country as a good US neo-colony).
But then came WWI and WWII, after which the European powers were all destroyed and weak, and the US became the Western Hegemon, with only the USSR, the Eastern Hegemon, as a serious military rival.
So the US made all the NATO nations into neo-colonies. The USSR suggested that Germany be re-unified like Austria, as a neutral, demilitarised nation, but the US said, 'NO! West Germany will be part of NATO, heavily armed to defend against Soviet aggression,' so the USSR made East Germany a member of the Warsaw Pact (formed as a reaction to NATO, but described in my history and geography books as preceding NATO and forcing the US to create NATO to stop the Warsaw Pact from annexing all the rest of Europe plus the UK).
And then the USSR collapsed, and the US became World Hegemon. Most of the Warsaw Pact were absorbed into NATO, including the Baltics, formerly unwilling parts of the USSR, forced into the USSR by Stalin during WWII.
So the US, as World Hegemon, started attacking countries for reasons not altogether clear. The nations attacked did not seem like serious threats to the US. Noriega said he did everything the US told him to do, but the US still invaded Panamá, killed a lot of Panamanians, and sentenced Noriega to Life in Solitary Confinement in the worst cell in the gaol, for reasons no one knows.
Meanwhile, the PRC had a falling out with the USSR. Britain and France had drawn all the International Boundaries in Eurasia and Africa, and the USSR figured the UK/French-drawn boundary between the USSR and the PRC was too far to the north, while the PRC figured the UK/French boundary was too far to the south.
So the PRC ping-pong team, at a tournament in Japan, invited the US team to come to the PRC. The US team asked, were told they could and should go, so they went.
And then Nixon went to the PRC and made a deal with Mao: the US would start moving factories to the PRC where the labour would be much cheaper than in the US, and the PRC would see how much better Capitalism works than Communism.
So now the nominal PRC economy is about half the nominal American economy, but at PPP, the PRC economy is about 25% larger. And the PRC is the world's biggest exporter, exporting about 25% of all the world's exports, and rising rapidly (from about 0% when the ping-pong team and then Nixon went to the PRC).
So the PRC now exports a lot to Latin America and imports a lot from Latin America. Venezuela is a significant source of PRC energy imports. And the PRC does not want the US to make Venezuela into a US neo-colony under a Nobel Peace Prize laureate who has promised to return Venezuela to a pure, unadulterated US neo-colony, with the locals getting paid nothing or next to nothing to do all the work to produce and send cheap oil and minerals (and bananas?) to the US.
And Russia, for reasons probably related to the Cuban Missile Crisis, have also sent lots of weapons to Venezuela.
So what happens now? WWIII anyone???
