The party that said it was okay to "meddle" in the affairs of other countries. The party that said,
The fact of the matter is that we, this generation of Americans, are the first generation of our country ever to be involved in affairs around the globe. From the beginning of this country, from the days of Washington, until the Second World War, this country lived an isolated existence. Through most of our history we were an unaligned country, an uncommitted nation, a neutralist nation. We were by statute as well as by desire. We had believed that we could live behind our two oceans in safety and prosperity in a comfortable distance from the rest of the world...Today, Democrats, and others like Ron Paul, Osama bin Laden, and Jeremiah Wright, say that the terrorists attack us because we have meddled in their affairs. We have bases in their countries, we support Israel too much, etc. Basically, it's our own fault that they don't like us, and if we would just stop all the meddling then they would leave us alone.
...We find ourselves entangled with apparently unanswerable problems in unpronounceable places. We discover that our enemy in one decade is our ally the next. We find ourselves committed to governments whose actions we cannot often approve, assisting societies with principles very different from our own...
...We cannot return to the day of the sailing schooner or the covered wagon, even if we wished. And if this Nation is to survive and succeed in the real world of today, we must acknowledge the realities of the world.
That meddling started with Democrats half a century ago.
