Buchanan's 3/25 column:
When Greek patriots sought America's assistance, Daniel Webster took up their cause but was admonished by John Randolph. Intervention would breach every "bulwark and barrier of the Constitution."
"Let us say to those 7 million of Greeks: We defended ourselves when we were but 3 million, against a power in comparison to which the Turk is but as a lamb. Go and do thou likewise."
But Randolph, and by extension Buchanan, don't have the history quite square. Our rebel colonist forefathers had help.
Quoting directly from Wikipedia, bold added:
France, Spain and the Dutch Republic all secretly provided supplies, ammunition and weapons to the revolutionaries starting early in 1776. After early British success, the war became a standoff. The British used their naval superiority to capture and occupy American coastal cities while the rebels largely controlled the countryside, where 90 percent of the population lived. Then, the Continentals' unexpected victory and capture of a British army at the Battle of Saratoga in 1777 convinced France to openly enter the war in early 1778, bringing the revolutionaries' military strength into balance with Britain's. Spain and the Dutch Republic—French allies—also went to war with Britain over the next two years, threatening an invasion of Great Britain and severely testing British military strength with campaigns in Europe—including attacks on Minorca and Gibraltar—and an escalating global naval war. Spain's involvement culminated in the expulsion of British armies from West Florida, securing the American colonies' southern flank.
French involvement proved decisive, with a French naval victory in the Chesapeake leading to the surrender of a second British army at the Siege of Yorktown in 1781.
I guess "Foreign aid for me, but not for thee" is Pat Buchanan's creed.
