This, then, is the choice confronting Republican primary voters in 2016: Whether to continue the traditional, Reaganesque foreign policy that has been championed by every Republican presidential nominee for decades or to opt for a Jacksonian outlook that is as crude and ugly as it is beguiling....Of the successes, Grenada is not 'Reaganesque' but actually Reagan's policy.
[L]ong experience shows that America has been most successful in achieving its objectives in precisely those places—such as Germany, Japan, Italy, South Korea, Bosnia, and Kosovo—where it has kept troops for decades and fostered new regimes to replace the old. Occasionally, as in Grenada or Panama, the U.S. can achieve its objectives and pull out. But in numerous other instances, such as Haiti, Somalia, Lebanon, and Iraq, an overly hasty pullout has sacrificed whatever gains U.S. troops have sought to achieve.
The close second of the successes is Panama, which his former Vice President did. So the two examples of 'occasional' successes of the Jacksonian type are the two most Reaganesque successful policies.
The commitment to long stays are all someone else's, whether successes or failures. Germany and Japan are Trumanesque, and were already long solidified by the time Reagan got there. South Korea is much the same. Bosnia and Kosovo are Bill Clinton's projects, well after Reagan had retired from the stage.
Among the failures, Clinton's were Haiti and Somalia. The Iraq pullout was Obama's decision.
Lebanon is the only one of the failures that can be laid at Reagan's door, and that mission was a United Nations force. Reagan withdrew at the same time as the French, who made up a strong component without which we'd have had to have committed forces much more heavily to a conflict in which our local allies were collapsing. If the argument is that we should have made an Iraq out of it, OK, but there's no reason to suggest that such a policy would have been "Reaganesque." What Reagan himself chose to do was the opposite.
Reagan himself took a Jacksonian approach in Grenada and won; his VP later became President and did the same thing in Panama, and won. Reagan took the internationalist approach favored by Bill Clinton in Lebanon and lost. Perhaps he could have won if he'd doubled down, but that isn't what he himself chose to do.
So the most obviously "Reaganesque" policy really is the Jacksonian policy. Reagan kept his Long, Twilight conflict cold, and used hot war only when victory could be had quickly or when there was a large international coalition backing the play. George H. W. Bush did the same thing -- Panama, but also the Gulf War with its huge international coalition. The other policies may be wise or foolish, but they aren't "Reaganesque."
