I can't speak for Speedy, but I have never voted for a Democrat in my now long-life, have always voted for the most conservative viable Republican candidates.
That word "conservative" has always been defined by men known as "Mr. Conservative" such as Ohio Senator Robert Taft in the early 1950s and Arizona Senator Barry Goldwater in the 1960s and Ronald Reagan in the 1970s and 1980s.
From the 1990s to his death in 2021, "Mr. Conservative" was Rush Limbaugh.
None of those men, those "Mr. Conservatives", were strict isolationists, not even Robert Taft under Pres. Eisenhower.
All supported America's allies, including NATO and the US Containment Policy towards communism in Asia & elsewhere.
All realized that American peace and prosperity depended entirely on the post-WWII world order that we were now critical to enforcing.
Even Donald Trump is far from an isolationist and fully understands that world peace and American prosperity depend on the strength of American leadership and the deterrence value of our military forces.
Since WWII it was always Democrats who shied away from such leadership, who hated "war mongering" and wanted to "give peace a chance", "make love not war", have "detent" with the Soviets and ignore the Chi-Com threats in Asia.
Sure, Democrats have always been quick to jump into wars, usually without a plan for victory, but then often just as quick to turn tail and run for the hills, surrendering as ignominiously as possible, with Vietnam and Afghanistan being prime examples.
"Stay the Course" is the Conservative Republican outlook.
"Hell no, we won't go" is Democrats saying what they truly believe.
