And here is Justin Logan:
Rumors that the GOP is returning to its isolationist roots are wildly exaggerated.
In fact, rumors that the GOP's roots were ever especially isolationist are exaggerated too.
Republicans first got tagged with the isolationist label when Massachusetts Sen. Henry Cabot Lodge led the opposition to the Treaty of Versailles after World War I. But his opposition to a stupid treaty in the wake of a misguided war wasn't necessarily grounded in isolationist sentiment. Lodge was an interventionist hawk on both WWI and the Spanish-American War. Lodge even agreed to ratify President Wilson's other treaty, which would have committed the U.S. to defend France if it were attacked by Germany.
Or consider the famously isolationist Sen. Robert Taft (R-Ohio), a role model of former Rep. Ron Paul (R-Texas). As a presidential candidate, Paul routinely touted Taft's opposition to U.S. membership to NATO as proof of the GOP's isolationist roots. But Taft also supported the Truman Doctrine and, albeit reluctantly, the Marshall Plan. He promised "100% support for the Chinese National government on Formosa [Taiwan]," and wanted to station up to six divisions in Europe. What an isolationist!
Many supposedly isolationist libertarians are for free trade and easy immigration but also want to shrink the military. Many supposedly isolationist progressives hate free trade and globalization but love the United Nations and international treaties.
Krauthammer is absolutely right that the GOP is going to have a big foreign policy debate — and it should (as should the Democrats). I'm just not sure bandying around the I-word will improve or illuminate that debate very much.
You should know three things about these [isolationist] claims. The first is that they are nonsense. Rand Paul, Rep. Justin Amash, and other skeptics of reckless foreign wars and secret government spying on Americans aren't isolationists. They're prudent conservatives who take the Constitution seriously and rose to power amid the wreckage of the George W. Bush administration, which destroyed the GOP advantage on national security and provided a good example of how not to conduct foreign policy.
