It was not difficult to define American geopolitical strategy over the seven decades following World War II — at least until 2009. It was largely bipartisan advocacy, most ambitiously, for nations to have the freedom of adopting constitutional governments that respected human rights, favored free markets, and abided by the rule of law. And at the least, we sought a world in which states could have any odious ideology they wished as long as they kept it within their own borders. There were several general strategic goals as we calculated our specific aims, both utopian and realistic.
(1) The strategic cornerstone was the protection of a small group of allies that, as we did, embraced consensual government and free markets, and were more likely to avoid human-rights abuses. That eventually meant partnerships with Western and later parts of Eastern Europe, Great Britain, and much of its former Empire, such as Australia, Canada, and New Zealand. In Asia, the American focus was on Japan, the Philippines, South Korea, and Taiwan. The U.S. military essentially guaranteed the security of these Asian nations, and they developed safely, shielded from Soviet or Chinese Communist aggression, and more recently from Russian or Chinese provocations.
(2) The U.S. also sought a stable, globalized world, predicated on free commerce, communications, and travel. This commitment on occasion involved ostracism of, or outright military action against, rogue regimes of the sort run by thugs like Moammar Qaddafi, Saddam Hussein, Slobodan Milosevic, Manuel Noriega, or the Taliban. There was no predictable rule about what offenses would earn U.S. intervention, and there was plenty of argument domestically over what should properly prompt such action. Perhaps a general observation was that rogue dictatorships that began killing Americans or lots of their own people, or that invaded their neighbors or threatened U.S. interests were most likely to be targeted.
(3) The U.S. tried to combat terrorism, whether, as in the past, Communist-inspired or, more recently, prompted by radical Islam. In the latter regard, the U.S. sought to make the world unsafe for al-Qaeda, Hezbollah, and various terrorist groups funded by Iran and, more stealthily, by opulent Persian Gulf autocracies and rogue Middle East regimes like that of the Assads in Syria. Without the American war on terror, the world would have been an even more dangerous place.
